Hi, I have an alix board running openbsd 5.5 that I've been using as a
router for the past few months.  It's worked great until yesterday
morning when it suddenly stopped connecting to the modem.
I spent yesterday messing with the settings which may have made the
problem worse :P

It sends a few dhcpdiscover requests and then gives up.
The LAN works fine and other devices can connect to the modem just great

here is dmesg and netstat -rn
