There's a section on the unaligned trap errors in the FAQ:

Sounds like your routing is backwards.

Make sure eth0 is set up with the correct netmask, etc. If it is, a route
should be set that directs all of the traffic for the LAN subnet to it.
You can see your routing table by typing "route" or "netstat -r".

Also, ppp0 should be set as your default gateway. That way any packets
for addresses that are not in your routing table will get sent out the PPP
link. Do not set a gateway for eth0 -- it should only be routing packets
to the local ethernet.
