Even then, if you have the same IP's on both networks you will run into problems with routing and ARP entries on the FreeBSD machine. If you are looking to connect the 2 networks together, run a different ip range on the (test) network, like the 10.0.0.0 or 192.168 network. If you are not connecting to the internet then you will not need to run NATD, just make sure that the gateway address of the machines on both sides are pointing to the corresponding FreeBSD interface IP. ******************************************************************* Nick Rogness Shaw's Principle: System Administrator Build a system that even a fool RapidNet, INC can use, and only a fool will nick@rapidnet.com want to use it. ******************************************************************* To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
