I only have one interface, my ethernet card, and what I = want to do is listen for UDP packets on a port, say 20000, and redirect = these packets to some destination, say my.host.com:20000. So far I have: 1. Recompiled the kernel with the IPFIREWALL and IPDIVERT options. 2. Set firewall_enable=3DYES, firewall_type=3DOPEN, = gateway_enable=3DYES, natd_enable=3DYES, natd_interface=3Dde0 in = rc.conf. 3. Added natd to /etc/services. 3. Started natd with "-redirect_port udp my.host.com:20000 20000 -n = de0". I have then tried sending a UDP packet to the machine at that port, = but it doesn't seem to be listening properly. I tried running natd with = the -verbose option to debug it, but it never shows any output. Please = help! -Louis Valentine ------=_NextPart_000_0007_01C02575.E5E64A50 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=3DContent-Type content=3D"text/html; = charset=3Diso-8859-1"> <META content=3D"MSHTML 5.50.4207.2601" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff> <DIV><FONT face=3DArial size=3D2> Hey, I'm trying to setup my = FreeBSD box with=20 4.1-RELEASE to act as a UDP router.
