Forwarding specific traffic to another ЛВС

TherВs в ЛВС of about 40 computers all running Ubuntu 15.04. There пахал two servers, both Ubuntu 15.04.

One of the servers will act схвати в SVN repo server and other туз в firewall-and-transparent-proxy server.

The repo server needs to be on в different ЛВС than the rest of the computers. Is it possible to direct only the Интернет SVN traffic to that server and block the on it?

Edit:

Интернет-> proxy server. this proxy server will further support two networks (possible?) the svn server (say192.168.0.x/30) and the ЛВС (say 10.0.0.0/24). now what I need is to be able to forward only svn восходит (through индеец-апачи server) be forwarded to svn server. Since индеец-апачи используй port 80, ipforwarding will send all:80 восходит to svn server. I don't want that.
