      Can you show a picture of your WAN interface configuration page?  The one connected to your DSL modem??

          Your gateway cannot be the same as the IP on its own interface.

            SORRY ABOUT THAT!  Slight oversight the last time I reset to defaults.  >_<

            I've set it to the proper 192.168.2.1 now.  (which it always has been except for the very last time I was setting it back up in a hurry and didn't pay attention).  =/

            Ok, so with that properly in place this is the situation:

            Still can't get a connection THROUGH pfSense.  (even though it seems to be FULLY communicating over both the WAN port and the LAN port).

            When I run a traceroute from PFSENSE this is what I get:

            netstat -rn -f inet; traceroute -n 8.8.8.8

            And AGAIN still not showing ANY states or ANYTHING in the firewall logs (even with logging turned on for the default rule.  It won't even show what it's NOT blocking.  It's just empty as always.)

              Ok, so check this out as well…

              I'm connect to the LAN port, so I'm testing pings on my laptop THROUGH pfSense and this is what I get:

              So it'll respond to a ping on the port I'm directly connected to AND pass the ping along to the WAN interface, BUT it won't let anything past it.  =/

                I skimmed your posts but didn't see so hope this isn't redundant…

                What do your outbound LAN rules and outbound port rules look like?

                  They're the factory defaults for right now.  Since I've reset everything.

                  The ONLY thing I've changed on the rules is that I turned logging on for the "Default allow LAN to any rule".

                  Attached are some printscreens.

                    On the    /firewall_nat_out.php  page-

                    Try choosing "Manual Outbound NAT rule generation"    save and see what results you get…

                    Assuming also that you have unchecked the last two boxes on your WAN interface page...    "Block Private Networks" and "Block bogon networks"      Gotta ask...    ;)

                      Had just blocking of Bogons checked, so I unchecked it.

                      Blocking of local addresses was already UNCHECKED cause I know that with these DSL connections they're using local IPs so I wouldn't want that checked.

                      I turned on manual NAT out as you suggested and attached is a printscreen of what that looks like now.

                      I'm still having the same results.

                        My next step would be to verify that (say) a ping from LAN client computer to 8.8.8.8 was getting to the pfSense LAN interface. (Packet capture on the LAN interface, displaying just traffic to selected destination.)

                        If you don't see the traffic in the packet capture then I would look at the IP configuration of the client: Does it have the correct IP address for its default gateway? (Should be the IP address of the pfSense LAN interface.) Does it have the correct MAC address for that IP address?

                          Packet captured pings from laptop through the LAN interface (which all came back as "Request timed out." on my laptop) and this is what the capture looks like:

                          16:38:32.824386 00:1b:38:62:d0:1a (oui Unknown) > 54:04:a6:f3:2b:05 (oui Unknown), ethertype IPv4 (0x0800), length 74: (tos 0x0, ttl 128, id 29038, offset 0, flags [none], proto ICMP (1), length 60)

                          As for the MAC addresses: I checked my arp tables on my laptop and all of the correct MAC addresses show as being associated with the correct IP addresses for both the WAN and LAN interfaces.  So everything is good there.

                            So now with the same ping running, does a packet capture on the WAN interface show the ping leaving the pfSense box? If so, what is the source IP address?

                                I would really like to know where traffic is stopping inside pfSense.  The above shows that it's tracking and trafficking my echo-requests…. but no echo-replies whatsoever.  Just doesn't make sense.

                                So it's showing that when I tell the WAN to send off data, IT DOES and TRACKS IT!  But if I try to send data THROUGH pfSense (from the LAN to the WAN) I get nothing.  Just does not make sense.

                                  You have turned off NAT in pfSense (at least for LAN to WAN traffic). If NAT was turned on the source address (as seen at the WAN interface) for the ping to 8.8.8.8 would be the pfSense WAN IP address.

                                  I suspect your ADSL router doesn't have a route to the subnet of the pfSense LAN interface hence it doesn't know on which interface to forward packets with destinaion IP address 192.168.168.100.

                                  You should turn NAT on in pfSense or add an appropriate route to your ADSL router.

                                    Well, I've turned Dynamic Routing Version 2 ON in my DSL router.

                                    And I renabled automatic NAT again in pfSense (since turning it to manual didn't make a difference).

                                    Is there anything else I need to enable in pfSense in order for it to send RIP data back and forth between the two routers?

                                    While I was remoted in to my laptop (using LogMeIn)  I switched it back over to use the pfSense as it's default gateway and lost my connection and can't get it back (which I expected).  So obviously traffic still isn't flowing through it.  I'll have to continue work on this tomorrow morning since I'm at home now.

                                        Thank you for any and all help in setting up my equipment.  If setting my dsl router to bridge mode will simplify, speed up, make more stable or just all around better my connection I will be more than happy do it.

                                        Now, please don't take this the wrong way as me being rude, I just want this post to get back on track… so I'll reiterate:
                                        It's not my equipment that is the issue here.
                                        I AM HAVING THE SAME PROBLEM WITH 1 DSL LINE WITH A ROUTER, 1 T1 LINE USING AN ADTRAN CSU/DSU, AND 1 T1 LINE USING A CISCO CSU/DSU TESTED WITH ANY AND ALL PORTS ON MY PFSENSE.

                                        ALL DO NOT WORK.  ALL WITH THE SAME EXACT SYMPTONS.

                                        It is NOT equipment OR how I've configured pfSense.  I've had pfSense up and running perfectly fine countless times.  It works great.  The problem is that out of no where when I've reset states one too many times it breaks and NEVER COMES BACK... that is UNTIL I COMPLETELY REINSTALL PFSENSE.  <<=== That is the issue.  There is a bug somewhere.  I want to know where and I want to know if there's a way to fix it without me having to re-install the entire program entirely.  Because currently re-installation is the ONLY way I have been successful in getting pfSense to work properly again.

                                        So again:  I can't communicate THROUGH pfSense with ANY equipment I plug on the other side of it.  Communication FROM pfSense itself works great!  But THROUGH it doesn't.  <<=== AND ALL OF THIS IS ONLY AFTER PFSENSE BREAKS.  After I've had everything setup and working hunky-dory and then I tweak a few firewall rules, reset states one too many times and BAM!  Broke and unreparable (unless someone can help me find the broken part and fix it).

                                        Again, please don't take offense, I just want to keep my eye on the prize.

                                          No worries-  I guess I missed any mention of you resetting states to make this happen….  I did lose my glasses so need new ones...

                                          But the DSL modem bridge comment...    Im of the opinion that you shouldn't double NAT unless there is no other way...  Bridge mode just keeps it simpler...

                                          In my case- Ive reset states here quite often and guess Ill go back and read more about resetting states and see if I can reproduce it here...

                                          Id be curious what your MBUF is at...

                                          And how many states your machine maxes out at...

                                            Well, I've turned Dynamic Routing Version 2 ON in my DSL router.

                                            Why?

                                            @soteriologist:

                                            Is there anything else I need to enable in pfSense in order for it to send RIP data back and forth between the two routers?

                                            Considering the difficulty you have had so far, why would that be a better solution than adding a static route to your DSL router or NATing in pfSense or adopting chpalmer's suggestion of using your DSL router in bridge mode?

                                            @soteriologist:

                                            While I was remoted in to my laptop (using LogMeIn)  I switched it back over to use the pfSense as it's default gateway and lost my connection and can't get it back (which I expected).

                                            Did you expect to lose your connection because your analysis of traffic paths showed a problem in that configuration or did you expect to lose the connection because your experience has shown you the network was fragile over configuration changes?

                                            @soteriologist:

                                            So obviously traffic still isn't flowing through it.  I'll have to continue work on this tomorrow morning since I'm at home now.

                                            What approach will you adopt for solving this?

                                            @soteriologist:

                                            Thank you for any and all help in setting up my equipment.  If setting my dsl router to bridge mode will simplify, speed up, make more stable or just all around better my connection I will be more than happy do it.

                                            DSL router in bridge mode is an option but depending on how the other equipment that connects you to the internet behaves you might might want to adopt a different approach.

                                            @soteriologist:

                                            It is NOT equipment OR how I've configured pfSense.   I've had pfSense up and running perfectly fine countless times.  It works great.  The problem is that out of no where when I've reset states one too many times it breaks and NEVER COMES BACK… that is UNTIL I COMPLETELY REINSTALL PFSENSE.   <<=== That is the issue.   There is a bug somewhere.  I want to know where and I want to know if there's a way to fix it without me having to re-install the entire program entirely.  Because currently re-installation is the ONLY way I have been successful in getting pfSense to work properly again.

                                            As best I can tell you need NAT in pfSense to pass traffic through since your DSL router doesn't seem to have a route to the LAN subnet downstream of pfSense. Somehow NAT was disabled in pfSense. Presumably as a consequence of a "few" firewall rule tweaks. I have no reason to believe that n+1 (n currently unknown) firewall state resets will disable NAT. Depending on what you call a firewall rule tweak (some action you get to through the firewall menu?) a firewall rule tweak can disable NAT.

                                            @soteriologist:

                                            Again, please don't take offense, I just want to keep my eye on the prize.

                                            OK, I promise not to take offence. Please do the same for me.

                                            I think the best ways you can accomplish your goal and help the pfSense project is to

                                            1. keep detailed notes on what you do and the consequences of change. I doubt any readers of these forums have the time or interest to do a random sequence of state table resets and firewall rule tweaks in the hope of chancing upon the same sequence you claim causes your problems. Without knowing what you did no-one can say for any certainty if the system is behaving correctly or you have found a bug.

                                            2. Before making a change answer the question "Why will this change make the behaviour I'm looking for?" If you can't answer that you shouldn't be making the change. If the change "doesn't work" find out why it doesn't work before making further changes. This will help you avoid making the same futile change in the future.

                                            3. Take small steps and test changes carefully so you can easily go back to a working configuration. If necessary, backup your pfSense configuration frequently and document the features of that backed up configuration. In most cases you should be able to recover desired behaviour by restoring a saved configuration file and rebooting.

                                            4.  Read a few articles (e.g. from Wikipedia or a good IP networking textbook) on IP routing and NAT. With three different connections to the internet through three different pieces of equipment it is quite possible you will not be able to replicate configuration for one WAN interface onto another. Future troubleshooting will probably be eased if you understand how each device connecting to the internet is supposed to behave.

                                            That's probably enough for now.
