Hi All... Until yesterday, I had to boxes existing happily together. There's a win box hooked up to, and talking to, a FreeBSD 4.3 box. The BSD box has, for 3 years (going through many version changes) as a DNS server, web server, mail server, Samba server, and, most importantly, gateway. I have NAT running, as well as IPFW. Up till yesterday, all was great. Then, today, I had a change in IP's, and a change in the gateway downstream from me. Now, I have this problem: FBSD --> Internet works FBSD --> Winbox works Winbox --> FBSD works Winbox --> Anything past the FBSD Box doesn't work I've changed nothing but the IP address in rc.firewall and rc.conf. I'm guessing I'm missing something simple, but i'm stumped... any thoughts or advice? I've pasted more info below. Thanks!!! --John ipfw show indicates nat is running: 00050 21392 9668930 divert 8668 ip from any to any via fxp0 while trying to do a traceroute from the windows box, tcpdump on the internal interface shows: tcpdump: listening on fxp0^M 200:03:09.004449 arp who-has merlin.wondermutt.net tell morgaine.wondermutt.net^ M 00:03:09.004528 arp reply merlin.wondermutt.net is-at 0:a0:c9:6c:a9:23^M 00:03:09.004745 morgaine.wondermutt.net.1044 > roaming-171-125.nss.udel.edu.domain: 1+ A? www.udel.edu.
