Seems like your trying to route through the linux box? Have you enabled ip forwarding and checked your iptables ruleset to make sure that either the default policy is ACCEPT or that you have specific rules in there that allow forwarding? [root at dc1-rhel5-32build001:~]# cat /proc/sys/net/ipv4/ip_forward 0 [root at dc1-rhel5-32build001:~]# iptables -L -n Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination [root at dc1-rhel5-32build001:~]# In the above case ip forwarding is disabled and the default policy is ACCEPT. nate
