Description

When I change the IP address on my LAN interface through the Set interface(s) IP address in the console, the network card which is associated with the LAN interface changes as well. The result is my LAN interface is not accessible anymore and no routing is working. Other interfaces still work.

It happened on both 2.0 and 2.0.1.

My LAN interface was em1 and after changing the IP address, it was fxp0.
I use PPPoE on the WAN interface to have pfSense handling my ISP public IP address.
fxp0 is the WAN card but is now using pppoe0 "interface". Could it be related? Maybe the anti-lockout rule reset has some relationship with this as well.

I can confirm an almost identical problem.

I have pfSense configured with 2 dual NIC cards:

bge0 -> PPPoE (WAN) to DSL
bge1 -> LAN
em0 -> OPT1 -> wireless
em1 -> not enabled

So what happens is, I'm using a different firewall, and I'm about to switch over to using the new pfSense firewall. The old firewall IP is 192.168.0.1. First I disconnect the old one from the DSL and connect the pfSense box to the DSL, and I make sure the pfSense logs in and gets a PPPoE connection. However, the pfSense box is sitting on IP 192.168.0.3 because it's not the gateway yet.

Then I go into the pfSense console, select assign IP to interface, select LAN, and change the IP to 192.168.0.1, bit count 24. It seems to go smoothly, but when the menu screen comes up, it shows that the LAN adapter is now bge0 instead of bge1. Then nothing works! It's quite a mess, so I have to go back to the old firewall, then re-assign my adapters. It's quite a pain.

I re-tested on the 2.1-BETA0-i386-20121014-1810 snapshot.

Unfortunately, the problem still occurs.

Right after installation and initial interface assignment, I changed the LAN IP from 192.168.1.1 to something I can access: here no problem.
Then I restored my configuration from the webGUI. After the reboot, every interface is setup as expected:

WAN: pppoe0
LAN: em1
OPT1: rl0
OPT2: em0
OPT3: xl0

I then changed the LAN IP and now I have this:
