There may be issues, but I have run dual homed FreeBSD since 1998.

Can you elaborate upon this?  It's not clear what you are trying to do.

So one NIC fails to work?  No traffic in or out?  Both nics?

Output of netstat -na would help us understand.

I originally said:
AFAIK, you cannot route between the two UNLESS you have
gateway_enable="YES" in /etc/rc.conf.

But what you mean is that you do not wish to route between the two 
subnets. The FreeBSD box is not a gateway.  It is merely dual homed.
