Thanks! to all who replied. I solved it by putting identical "GATEWAY=" clauses in each of /etc/sysconfig/networking/devices/ifcfg-eth0 /etc/sysconfig/networking/devices/ifcfg-eth1 This works without error, even though the gateway IP address in question is not accessible from eth1. I haven't tried taking the GATEWAY clause(s) out of the ifcfg files and moving it to the /etc/sysconfig/network file alone. Does anybody know if that's the preferred configuration option? Thanks!
