Hi There, I have a FreeBSD 3.1 box acting as a Firewall/Router. The box has two network cards(ed1 and ed2) and packet forwarding is working fine. Here is my problem: INTERNET----ROUTER -------ED1,ED2----------MACHINE BEHIND FIREWALL(MBF) The "machine behind the firewall"(MBF) has a resolvable ip address say (204.14.1.7) and is on interface ED2. The router is on ED1. I need it to be resolvable because I want it to be accessable via the internet. Packets go out from MBF but they don't come back. The problem is that the router(which I DONT have access to), when it receives a packet destined for 204.14.1.0/24 it does an ARP and gets no response. If I had access to the router all I would need to do is add the appropriate route and it would work fine, but unfortunately this is not an option. What I need is the FreeBSD box to respond to the ARP request(proxy arp) and forward the received packets to MBF. I've tried natd, ipfw fwd, proxy arp, and various combinations of the three. Can someone help me? Any thoughts would be sincerely appreciated...
