Multi homed proxy server

[Kevin Plew]

Is your firewall dropping the packets?( tcpdump or ethereal to check )

No packets dropped- iptables -L show no rules


> Is the DHCP server assigning the correct default gateways, dns info to
> both subnets?( traceroute and dig )
Yes

> Does traceroute from the proxy to a node with a problem go the correct
> way?
[root at newengland root]# traceroute -i eth1 10.10.11.50
