I have a system with two NICs with 4 ip addresses (eth0,1,2,3) on two different subnets (x.x.230.x and x.x.221.x).
Problem when our network Engineer shuts down one switch port, 2 ip's on same subnet will go down.
I am trying to setup these for redundancy if one of the ip's or switches go down, other will take over. I tried with different options with zoning and port forwarding, but it is not wotking for me.
My NICs are configured as follows:
eth0-x.x.230.16 int zone vlan1 eth1-x.x.221.1 ext.zone vlan2 eth2-x.x.230.26 int zone vlan1 eth3-x.x.221.11 ext.zone vlan2
I know it's possible to configure these NICs for redundancy - What am I missing?
