Here's the situation: we have a FreeBSD 3.2 machine running natd and ipfw with one external interface (205.164.160.26, 27-29 aliases), and one internal interface. To get to the entire internal network, we go through a compatible 2600 router with "route add 10.1.0.0 -netmask 255.255.252.0 10.1.3.20". While the internal network gets out fine, we're having trouble with natd re-directing from external to internal so outside people can get to the servers. Using tcpdump on the internal ethernet card, I see packets being sent to the correct internal machine then returning, however the client never gets anything back. While this would appear a firewall situation, the correct ports are opened up and quiet mode is off, showing no packets denied. We've setup several proxy servers running natd/ipfw where port-re-direction was used, and this is the first time there's been trouble. I was wondering if perhaps the static route command could mess things up? Any ideas greatly appreciated. -- "Your illogical approach ... does have its advantages." -- Spock, after being Checkmated by Kirk To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
