Hi all, I have a strange setup I am trying to get working. Initally I thought I could set it up by just setting up the correct routes. However after thinking about it I have convinced myself (maybe incorrectly) that I most likely need some sort of advanced NAT/routing setup. Below is a description of the networks involved: Local net (192.168.101.0/24) | | Linux machine eth1 (192.168.101.5)---- eth1:0 (10.140.227.245) | Iptables NAT/firewall | Linux machine wan0 (This is a sangoma wanpipe with a routable ip address) | ISP The 10.140.227.224/27 network is a private network that knows nothing about the 192.168.101.0/24 network and is not controlled by us. Previously they were run as 2 seperate networks. What we are trying to do is to be able to install some custom software on the local net machines (the 192.168.101.0 net) and have 5 specific subnets send the traffic down the 10.140... net and the rest of the non 192.168.... traffic out the wan0 interface. Currently the 192.168... net and the 10.140..... net are on the same wire. I could split them and put another interface in the linux box if necessary. Is this possible? If so can someone point me in the right direction on how? Does this even make sense? If not please let me know and I will try to explain further. FWIW the linux box is a Red Hat 7.3 box with all of the latest updates.
