It's the end of the week, and maybe I'm being dense, but I still don't get it: how do I tell the BMC to use eth1? Do I give it eth1's MAC address as a gateway?
No, use the IP and MAC of the gateway you wish it to use, as if you were configuring another network device that's on the same network as eth1 (assuming it's sharing the eth1 physical network port). THe important thing to remember is: The BMC is not eth1. It just happens to share the physical port you're plugging an ethernet cable into. It behaves like there's another computer inside your case, with a vampire tap on the ethernet port's cable.
For example, if this is your eth1:
$ ip -4 a show dev eth1 2: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 inet 10.0.0.5/24 brd 10.0.0.255 scope global dynamic noprefixroute eth1 valid_lft 567262sec preferred_lft 567262sec $ ip -4 route default via 10.0.0.1 dev eth1 proto dhcp metric 100 10.0.0.0/24 dev eth1 proto kernel scope link src 10.0.0.5 metric 100 $ arp -n 10.0.0.1 Address HWtype HWaddress Flags Mask Iface 10.0.0.1 ether 00:00:11:11:22:22 C eth1
Then you would pick an IP on your network (lets call it 10.0.0.6) and set the IPMI interface to use 10.0.0.6/255.255.255.0 and use 10.0.0.1 and 00:00:11:11:22:22 as the defgw MAC.
You won't be able to ping the IP from the same system, but it should be reachable from other systems on the 10.0.0.0/24 network above.
