Verify with your ISP. read below. Probably 209.88.252.104/30.

I can't understand what you are trying to say. SO I am following your diagram completely.

Your networks are .0/29 and .8/29. WHat are you trying to do here? 209.88.252.112/29 contains: 209.88.252.108 --> 209.88.252.115 > > route add -net 0.0.0.0 209.88.252.113 Why is your default route going to .113?

(pls, write the commands) Look at your /etc/rc.conf file. You should see a couple of lines: GATEWAY_ENABLE="YES" > > 2. Do i need another software? like gated or routed or > > natd? Not neccessary unless you want to exchange routes between machines. Your setup is very simple. Static routes should not be neccessary (Except your default gateway) and as long asip forwarding is on (GATEWAY_ENABLE) it should work. Also, the ISP should be holding the static routes for the following net, within their routers, or you will have to run a Dynamic Routing package like gated, Eitherway, make sure the ISP can get to your .112/29 network: route add -net 209.88.252.112/29 209.88.252.6/32 Nick Rogness - Speak softly and carry a Gigabit switch.
