I have noticed that natd (or something related) has stopped working though. On my system I have ed0 - outside interface to cable modem ep0 - inside to private network Using the following three ipfw entries: allow ip from any to any via ep0 divert natd from any to any via ed0 allow ip from any to any I am unable to use TCP,UDP services out of the ed0 line ( like telneting to a server on the internet ). I am also unable to telnet or ftp into the box from the private lan (it should be passed with the first ipfw rule). NOW, if I remove the "divert natd" line I can use TCP,UDP services out of the server on ed0 and I'm also able to connect to the box from the internal network. Strangely, I am able to send ICMP requests with and without natd running. If I run natd with the verbose flag and also do some tcpdump-ing, I notice that when I have natd running the packets seem to be going out the ed0 line fine, but there are no response packets returning (unless they are being silentely dropped). Since I had recently replaced my "ed1" (internal network) card, with the "ep0" I thought that maybe it was a bad card, but when I turn off natd, everything works fine. Other than the card switch, I haven't changed any other settings or anything, and I believe I have made all ed1->ep0 changes that are necessary in config files and such. Has anyone else noticed these problems, or is this just a dumb user problem :| ? Is there anything that I missed that could be causing these problems? Thanks, let me know if there is any more information I can provide /**************************************** * Mike Heffner * * Fredericksburg, VA ICQ# 882073 * * Sent at: 04-Apr-2000 -- 21:21:32 EST * * http://my.ispchannel.com/~mheffner * ****************************************/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ipfw" in the body of the message
