There are 3 NICs attached to it, 2 eepro100, and 1 ThunderLAN driver v1.14a. This box is being prepped to be a download server. GOAL: Requests are sent to each NIC via seperate IP addresses. All 3 are on the same subnet. All requests are load balanced via a DNS server. We want all requests to exit the same NIC that they entered. PROBLEM: All requests are satisfied via the last NIC (eth2). eth2 does 99% of the transmissions. With the configuration below it is possible to do load-balancing, both in and out, but it is not possible to secure shell to the box. If the "ip rule" lines are commented out, login is possible, but no outbound load balancing. OUR CONFIGURATION: ip route add 206.17.228.231 dev eth1 ip route add 206.17.228.232 dev eth2 ip route add 206.17.228.230 dev eth0 /sbin/route del default 2> /dev/null /sbin/ip route add default equalize nexthop via 206.17.228.2 dev eth1 nexthop via 206.17.228.2 dev eth2 ip route add 206.17.228.231 dev eth1 table 231 ip route add default via 206.17.228.2 dev eth1 src 206.17.228.231 table 231 ip route flush cache ip route add 206.17.228.232 dev eth2 table 232 ip route add default via 206.17.228.2 dev eth1 src 206.17.228.232 table 232 ip route flush cache ip route add 206.17.228.230 dev eth0 table 230 ip route add default via 206.17.228.2 dev eth1 src 206.17.228.230 table 230 ip route flush cache ip rule add from 206.17.228.231 table 231 ip rule add from 206.17.228.232 table 232 ip rule add from 206.17.228.230 table 230 WHAT AM I DOING WRONG?
