Hello folks, The last few weeks I've been hacking on a NAT-PT implementation for the FreeBSD operating system in my spare time. I tried to use the NAT-PT code in KAME's tree, but that was for FreeBSD 5.4 and didn't compile properly.
Because its implementation was also quite evil (hooks in the ip_input and ip6_input functions to capture packets), I thought: why not capture IPv4 traffic using pfil? That way we can also build it as a module. I also thought it would be more useful to send and receive IPv6 packets through a pseudo-interface, just like faith (except that you don't need the faithd). Today I'm releasing this code. It's also my 20th birthday, so instead of getting presents, I also have the honour of giving one away: http://g-rave.nl/projects/freebsd/natpt/distfiles/freebsd-natpt-20060412-birthday.diff One note: there are still a few caveats in this code: - IPv4 source port is the same as IPv6 source port - ICMP and FTP are not translated - Timeout value for the state table is just a guess (15 minutes). Any feedback would be welcome. :) Yours, -- Ed Schouten <[EMAIL PROTECTED]> WWW: http://g-rave.nl/
