My pfSense keeps breaking (novel inside…)
-
The only thing left for me to do is re-install and start from scratch… AGAIN.
But before I do that, I figured I'd post on here to see if someone had a suggestion to diagnose this shit and hopefully stop others from running into the same problem AND hopefully prevent me from running through it all over again a third time.
I figured if there truly is a horribad bug somewhere in the code, someone would want to know about it and get it fixed.

ok, so I turned on accessing the web configurator from the wan side. One of my internet connections is DSL which uses a wired/wireless router/modem combo. So I've plugged my laptop into one of the other wired ports on the little DSL router and can access my pfSense box through the WAN port there. So at least SOME traffic is flowing through that connection. But it's not showing up in the states/firewall logs.
Still no pings, webpages, email, etc are going through it though. :'(
Can't get a connection to the internet through the pfSense. :-\ -

There are still a number of alternatives, including plugging your laptop into the DSL router and attempting to access the pfSense WAN port.
One of my internet connections is DSL
What are the others?
So I've plugged my laptop into one of the other wired ports on the little DSL router and can access my pfSense box through the WAN port there.
Can you also access the management interface on the DSL router? What does it tell you about the WAN interface of the DSL router?
What is the interface type of your pfSense WAN interface? (Static? DHCP? PPP?)
Please post the output of of the pfSense shell command```
netstat -rn -f inet; traceroute -n 8.8.8.8
-
Tried pinging with pfSense's web configurator (under Diagnostics >> Ping) to both 4.2.2.2 and google.com (along with a handful of other sites) and get no response. Tried pinging the DSL router, and get a response. Tried pinging my laptop that is also plugged into the same router and get a response form my laptop's ip address.
Still nothing shows in states/firewall logs though?
I'll try that traceroute command.
-
Here are the results:
netstat -rn -f inet ; traceroute -n 8.8.8.8

You don't have a default route hence most of the traffic that would normally go out the WAN interface doesn't go out the WAN interface because there isn't a route saying that is where it should go.
Your pfSense WAN interface type is? (Depending on that I might be able to give you a pfSense shell command to add a default route.) But that won't help if the upstream link from your DSL router is broken. Can you get status of the upstream (to the Internet) link on the DSL router?
What version of pfSense are you running? Please post the version information from the home page of your pfSense box.
-
Hmm, you have no default route and no route to anywhere outside your network. Problem!
Is your WAN connection up? (or was it when you did this).
@soteriologist:I've already uninstalled all the packages.
The reason I suspected packages is that they sometimes either overwrite things they shouldn't or remove things they shouldn't when you uninstall them.
Uninstalling all the packages is not necessarily the same thing as never having installed them! ::)
Something has messed up your routing table, either directly or by messing up something that controls the routing table.

Edit: Typed too slow.

I'm able to get an internet connection fine through all of my WAN devices I've had in the past (and currently have) attached to pfSense. Even when I plug in using the same cables/ports that pfSense would use to those devices.
I ruled out any hardware problems at the get-go.
As for my current version:
Version 2.0.1-RELEASE (amd64)
built on Mon Dec 12 18:16:13 EST 2011
FreeBSD 8.1-RELEASE-p6As for the default route, I can check mark that box for the interface. Right now it's unchechked because I had a loadbalancing group created and had "Allow default gateway switching" under "System >> Advanced >> Miscellaneous >> Load Balancing" checked.
I can recheck to have just that default DSL line checked as the "Default Gateway" and uncheck the other setting… brb.
-
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:
netstat -rn -f inet; traceroute -n 8.8.8.8

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:
