My pfSense keeps breaking (novel inside…)
-
You need to set a default gateway even if you're policy routing your egress traffic. And uncheck the default gateway switching.
What type of WANs?
-
I just rechecked to have just that default DSL line checked as the "Default Gateway" and unchecked "Allow default gateway switching" under "System >> Advanced >> Miscellaneous >> Load Balancing".
Still no ping response beyond the router/modem it's plugged into.
Stil no internet connection.
Still nothing in state/firewall logs.Re-ran traceroute and this is what I have now:

The three WANs that I have are:
One DSL connection through a Verizon router/modem
One T1 through an AdTran DSU/CSU
One T1 through a Cisco DSU/CSUAT THE MOMENT I'm ONLY using the DSL for testing. Just to simplify things and because the entire company is actively using the two T1s at office. But when I had everything plugged in during off hours, they were all working fine until… well... everything stopped working. So I had to put everything back they way I had it in the very late hours of the night before everyone came back in the next day and BACK TO THE DRAWING BOARD!

traceroute: sendto: Host is down1 looks like your DSL router doesn't reply to the traceroute probes - that's allowed
2 "Host is down" suggests the DSL router's WAN link is down or for some other reason (also lost its default route?) it doesn't know where to forward the traceroute probes. -
I'm posting this connected through the DSL router. So I know for a fact the router is working great.
Here's traceroute from my laptop attached to one of the other ports on the DSL router:

Can you show a picture of your WAN interface configuration page? The one connected to your DSL modem??
-
Here are printscreens of both my Interface and Gateway setup for the WAN.
-
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:

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:

192.168.168.100 > google-public-dns-a.google.com: ICMP echo request, id 1, seq 120, length 40As 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?
