I am having problems getting tircproxy to work on FreeBSD 4.2 using IPF
version 3.4.8.  tircproxy compiles and starts up, but when a client
tries to connect, I get "ioctl: Invalid argument" or "Invalid address"
and the client ges an imediate connection reset by peer.

I have searched through the mailing lists and have found only one
reference to this problem: http://false.net/ipfilter/2000_01/0393.html.
 I contacted the poster and asked him if he was ever able to make it
work and he said no.

I have looked through the source files for tircproxy and found one
section of code in tircproxy.c that deals with ioctl which is:

                fd = open(IPL_NAT, O_RDONLY);
                if (ioctl(fd, SIOCGNATL, &natlook) == -1)
                {
                        perror("ioctl");
                        exit(-1);
                }
                close(fd);

Any ideas or suggestions would be greatly appreciated.

Thanks.
