From: Olvin <olvin@rambler.ru> To: ALT Linux Community <community@lists.altlinux.org> Subject: [Comm] iptables и port masquerade Date: Tue, 29 Nov 2005 17:49:03 +0200 Message-ID: <438C786F.90005@rambler.ru> (raw) Хочу сделать, чтобы при обращении к любому хосту сети на tcp-порт 2525 на самом деле происходило обращение на порт 25. Т.е. адрес получателя менять нельзя. Не получается. Посоветуйте что-нибудь. Вот, что я пробовал: [olvin@enigma olvin]$ sudo iptables -t nat -A POSTROUTING -p tcp --dport 2525 -j MASQUERADE --to-ports 25 [olvin@enigma olvin]$ sudo nmap -p 2525 localhost Starting nmap 3.81 ( http://www.insecure.org/nmap/ ) at 2005-11-29 17:37 EET Interesting ports on localhost.localdomain (127.0.0.1): PORT STATE SERVICE 2525/tcp closed unknown Nmap finished: 1 IP address (1 host up) scanned in 0.435 seconds [olvin@enigma olvin]$ sudo nmap -p 25 localhost Starting nmap 3.81 ( http://www.insecure.org/nmap/ ) at 2005-11-29 17:37 EET Interesting ports on localhost.localdomain (127.0.0.1): PORT STATE SERVICE 25/tcp open smtp Nmap finished: 1 IP address (1 host up) scanned in 0.437 seconds [olvin@enigma olvin]$
