One of my ubuntu servers has its interfaces automatically names as p33p1 and p34p1. I simply changed the old eth0/eth1 names to the new ones in these shorewall files and it has been working fine for a couple of years: * interfaces (obviously!) * hosts (because I have multiple subnets on both interfaces) * masq * tcinterfaces Why not just "grep -lir eth /etc/shorewall/ and edit the files?
