Description

Having upgraded from stable to 2.1-BETA0 (i386) (built on Mon Jun 11 03:04:03 EDT 2012), a strange issue has occurred. The WAN interface IP is configured as 31.24.0.195/26 and there's 3 IP aliases to this interface:

31.24.0.198/32
31.24.0.196/32
31.24.0.200/32

pfsense thinks the WAN interface IP is 31.24.0.196. This shows in a few different ways:

  • The IPSec Local IP is 31.24.0.196 - this causes ipsec to break.
  • None of the firewall rules permitting access to "WAN address" work - rather they allow access to 31.24.0.196 instead
  • I cannot edit the 31.24.0.196 IP alias as it says an alias cannot be the WAN address

Interestingly, changing the WAN IP subnet from /26 to /25 fixes this issue and pfsense correctly identifies its WAN IP. This is what I have put in place, presently, pending a better fix.
