I am having a problem where I am unable to communicate with a CentOS box from any subnet other than its own. I have verified connectivity across the subnets with different machines and my firewalls are allowing all traffic between subnets. This machine has an internal interface and a global interface. Any traffic originating on the 192.168.100.0 subnet communicates just fine but if I try to ping or ssh from a 192.168.140.0 subnet I get nothing. Here is the routing table below.
[root@webserv ~]# route
