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
