I have inherited a badly designed network, and have to keep it up. There's a machine running VMWare, and a pfSense VMWare appliance is acting as firewall and NAT. The network in use inside this NAT is 10.0.0.0/14. The pfSense appliance has two more network adapters, one connected to the internet, and one connected to another physical machine on a 10.139.251.104/29 network. What I am tasked with is to make that external machine visible to other virtual machines running behind pfSense. I have been banging my head against the wall, trying to figure out what sort of a rule do I need to create in pfSense and other VMS (which are running CentOS) to make this happen. Can anyone give me any ideas?
