m0n0wall Forum - WAN interface goes up down up down up down

I'll be honest, I have absolutely no idea what's going on here.

I noticed the Internet would be fine for about 20 seconds, then the next link I clicked it would just be like I wasn't connected. Looking at the log, I found:

Code:

Which I'm sure isn't quite right. My hardware is a Nokia IP440 with a 4-port Zylex NIC, where dc0 is one of those ports.

My config file is as follows:

Any suggestions? It may be related to a bug in FreeBSD, although the bug was filed for the re* interface with a different driver: http://lists.freebsd.org/pipermail/freebsd-bugs/2005-April/012562.html

It's still going a few hours later. It's usable. But very very irritating having some connections work and others just drop without warning. I'm thinking of just switching to OpenBSD and configuring pf manually. I can do it but it's effort. I'd rather not exert effort.
