If you don't have this in there, then you are not doing NAT, just packet filtering. man ipnat man 5 ipnat Marco Radzinschi E-Mail: [EMAIL PROTECTED] Wed Dec 25 17:08:12 EST 2002 To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
Re: Help with IPF and IPNAT
You didn't send any rules for it? Do you tune them? Try to read this about ip filter installation and sturtup-time pulling. http://www.freebsddiary.org/topics.php#ipfilter [EMAIL PROTECTED] wrote: Argh!

Help with IPF and IPNAT
Argh! I've been pulling my hair out trying to get my NAT gateway going. I have two interfaces, one external and internal, servicing a private LAN. >From the LAN I can ping the internal interface and the external interface, but I can't get past the ext. interface.
