Problem replacing Cisco ASA with pfSense on Comcast
-
Yes, the two boxes are right next to each other with just the one cable connecting them. And I’ve tried several different cables.
Right now I’ve got things in an isolated test setup since it’s a workday and we need our Internet access (so we’re back on the Cisco for now). I’ve got the LAN connected only to my laptop and the WAN connected to a dumb switch. WAN still says no carrier regardless of whether I use igb0 or em0. Still no carrier on the WAN side.
-
Take a KNOWN GOOD 8-conductor cable and loop igb0 and em0 (plug one end into igb0, the other end into em0)
Execute this in Diagnostics > Command Prompt: ifconfig -a
Post the output.

And in doing this the WAN interface status shows up in the web tool. Weird that with a dumb switch or my cable modem connected it’s down.
-
Yeah. Fix your layer 1/2. The igb0 and em0 should both auto-mdx. Hard to say what the problem is from remote.
-
Man I think I’m prepared to say I’m an idiot.
I think I misread which port was which (someone asked me that early in this thread). I assumed both built-in NICs were em0 and em1 and the add on card was igb0. Reasonable right? After all the hardware for the built-in ports is the same on the motherboard. Well, it looks like one built-in is em1 and the other is igb0 and the add on is em0. Right now I have the add on card connected to the dumb switch and configured as the WAN port and it’s showing UP.
Guess I should never assume anything. BTW does the underlying Linux of pfSense have a command line tool to blink the network ports? That would be the final confirmation.
-
I spoke too soon. I think the web interface isn’t updating status properly. Em0 is the WAN port, and it’s showing UP connected to my dumb switch now after doing the cross-connect to igb0.

"underlying Linux of pfSense have a command line"
pfsense is not linux its on freebsd… Big difference!!!
As to your em sure you should be able to use this
https://www.freebsd.org/cgi/man.cgi?query=em&apropos=0&sektion=0&manpath=FreeBSD+11.1-RELEASE&arch=default&format=html#FILESFILES
/dev/led/em* identification LED device nodesEXAMPLES
Make the identification LED of em0 blink:echo f2 > /dev/led/em0
Turn the identification LED of em0 off again:
echo 0 > /dev/led/em0
igb should be able to do it too
https://www.freebsd.org/cgi/man.cgi?query=igb&apropos=0&sektion=4&manpath=FreeBSD+11.1-RELEASE&arch=default&format=htmlWhen get home will validate with my 4860
-
You sure you actually know what port is what?
-
Yeah, I feel really stupid, especially after the "you sure you know what port…" comment. I wish I knew that blink command yesterday!
Thanks for all the help everyone. Now does anyone know why pfSense would call the two built-in ports em1 and igb0 and the add on card em0? Makes no sense to me at all. That's what tripped me up.
-
The operating system enumerates the ports. It has to do with the PCI bus they are on, etc. Every motherboard is different. You need to look at the MAC addresses and be sure you're talking to the correct port.
