Hello... I've got a strange trouble... FreeBSD 6.2 amd64 as nat-router: rl0 85.249.249.249 -> ISP fxp0 10.0.0.1 -> My Internat Net natd/ng_nat ipfw: allow all from any to any WinXP client machines work fine behind nat, but WinVista, FreeBSD (5.5/6.2) clients don't. It's very strange but it's unable to establish any TCP internet connection from non WinXP host. ICMP and UDP packets flows normally. For example, I can ping host ya.ru, get DNS-reply from internet servers, play games via UDP, but i can't view web pages, open shh session and just can't "telnet" to any port!!!! Traffic from/to my net is not filtering by firewalls at all. I've tested it with natd ang ng_nat - there's no difference! I've tried to solve this problem during last week =( Unfortunately, i can't. Now i'm going to try using pf or ipfilter instead of ipfw or ever reinstall server OS and may be change freebsd architecture to i386. Any ideas ? P.S.Sorry for my bad english.
