So (real world case) I've got a server that's got a 1G ethernet connected= to the public net, a 1G ethernet that's a cluster management network, and a 10G ethernet that connects to our HPC clusters. And I want to add iptables rules that distinguish based on interface. Cur= rently I can nail the management net to eth0, the public net to eth1, and the 10= G to eth2, and then just add =22-i eth1=22 or whatever in the iptables ruleset= . I really don't care if the 0/1/2 move around - but if we're not having na= iled-down interface names, what will take the place of '-i ethN' in iptables? > People who need predictable interface names should just manually > configure custom/descriptive names, or names which are reliably > derived from the hardware, like firmware-provided names or the pci > slot number.
