Hello! I'm trying to setup my dual interface machine to act as an ftp proxy for my home LAN. The machine has two interfaces: ep0 (10.10.0.2/28) and ep1 (connected to the cable-modem, with DHCP-obtained settings). It is a real shame, this part is so poorly documented, but I did find the /usr/src/contrib/ipfilter/rules/ftp-proxy, which was a little cryptic, but combining it with http://www.dvl-software.com/freebsd/natrules.htm I setup the /etc/natrules as follows: map ep1 0/0 -> 0.0.0.0/32 proxy port ftp ftp/tcp Ftp-ing to the server goes fine, I can log in. But whenever a data connection is attempted -- say, for ``ls'', the nat-machine panics. The panics are different depending on whether the ftp-client is on the same machine or on some other machine on the LAN. Actually, as I just found out, it can crash anytime after the rule above is loaded -- I guess, any incoming attempt can trigger it :( I'm rebuilding the kernel without the omit-frame-pointer now, to get meaningful information from the panic screen. But if you know what I'm doing wrong -- just tell me now :) Thanks, -mi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
