Need help about Internet Sharing Connection in FreeBSD

[Quang Nguyen Dang]

In Local Network we have a Server Internet Gateway with address Gateway 10.10.1.1 connected internet from WAN and then share to other computers. Now I'm making a new server with FreeBSD 5.3 and I want to share Internet from this new Server to make cheaper (5cents/MB). How to share it? Please help me. I' using UTM for Billing System. http://www.netup.info
