Static routes - yes, thanks, I will probably do exactly this instead of the default gateway!

Device-adresses (which is meant by the subchannels config value) are sufficient to identify an OSA card, MAC-addresses are a bad idea in a virtual environment. But I am not sure what would happen on RHEL4 if your eth1 had smaller device-addresses than eth0. In former times the interfaces were mixed up, maybe they fixed it. > As to the GATEWAY definitions: as far as I can see the two OSAs belong to > different subnets, > I thought each subnet has ist own default gateway? No, there is only one default gateway for your system, this is why it is called "default" gateway. You can define static routes on specific subnets which are not routed through your default gateway if this is necessary.
