I had Linux Virtual Server (tunnelling) working fine when I had all the
servers in the same subnet, but when I moved 'em out from behind the
firewall and into their places in the real world, I can't seem to get
it working again. Any hints would be greatly appreciated. Here's how
it's being setup...
Load Balancer, linux 2.0.36, vs-0.8:
eth0: 192.168.4.42 netmask 255.255.255.224 (net 192.168.4.32/27)
ifconfig eth0:0 192.168.4.37 netmask 255.255.255.255 broadcast
192.168.4.37 up
route add -host 192.168.4.37 dev eth0:0
ippfvsadm -A -t 192.168.4.37:23 -R 192.168.5.124
Server, linux 2.2.5ac3:
eth0: 192.168.5.124 netmask 255.255.255.192 (net 192.168.5.64/26)
ifconfig tunl0 192.168.4.37 netmask 255.255.255.255 broadcast
192.168.4.37 up
Load Balancer ifconfig -au/routing:

And ippfvsadm -L says:
Protocol Local Addr:Port ==>
Remote Addr Connections
...
TCP 192.168.4.37:23 ==>
192.168.5.124 2
So, I'm getting that far, at least...
