Re: Any recent changes for ipfilter/ipnat?

You updated the nic entries in /etc/ipnat.conf, so it matches the new driver name?

Yes. I renamed my old /etc/ifconfig.nfe0 to /etc/ifconfig.tlp0 (and removed the various cksum offloads that tlp doesn't do), and I editted the /etc/ipnat.conf file to change all references from nfe0 to tlp0.


I've also verified (using tcpdump) that the packets arriving on tlp0 are being forwarded without having been NAT'ed. It would be pretty hard for me to receive any reply packets, since they would be addressed to my
RFC1518 private network.  :)


Here's my network topology:

   (the Internet)   66.92.189.133       192.168.2.250   (private net)
   ------------------------------       -----------------------------
                                |       |
                            re0 |       | tlp0
                           -------------------
                           |                 |
                           | gateway machine |
                           |                 |
                           -------------------

I have an empty /etc/ipf.conf (it's only there because I need one to start ipf, which is required to run ipnat). Here's my /etc/ipnet.conf

        {102} cat /etc/ipnat.conf
        map tlp0 192.168.2.0/25 -> 0/32 proxy port ftp ftp/tcp
        map tlp0 192.168.2.0/25 -> 0/32 portmap tcp/udp 40000:60000
        map tlp0 192.168.2.0/25 -> 0/32

        {103}
