Use either the "me" pseudo-address or trigger on the interface. A few rules copied out of my current ipfw configuration: 00600 allow tcp from me to any setup 01400 allow udp from me to any dst-port 53 keep-state 01500 allow udp from me to any dst-port 123 keep-state 01600 allow udp from 69.1.30.0/24 67 to me dst-port 68 01700 allow udp from me 68 to 69.1.30.0/24 dst-port 67 -- David Kelly N4HHE, [EMAIL PROTECTED] = The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I believe your current omask will work; try it and see.
I use
omask="255.255.255.0"
onet=`ifconfig fxp0 | grep "inet " | awk '{print $2}'`/24
oip=`ifconfig fxp0 | grep "inet " | awk '{print $2}'`
You could probably simplify that with
oip=`ifconfig fxp0 | grep "inet " | awk '{print $2}'`
onet=${oip}/24
but I haven't tried it.

Re: Help setup home network when gateways, ip asigned by DHCP
You may want to try IP Filter instead. In my opinion, it's rule syntax makes it much easier to work with DHCP. http://www.obfuscation.org/ipf/ipf-howto.html#TOC_29 - Original Message - From: "Rod Person" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, August 21, 2003 6:17 PM Subject: Help setup home network when gateways, ip asigned by DHCP > I have been trying to setup a home network for some weeks now.
