우분투 포트포워딩

진짜 요즘 리눅스가 좋아졌다는 생각이 드는게..

예전에 포워딩할때 iptables 로 어떻게 하고 했던것 같은데

우분투에서 iptables 어떻게 만지나해서 한참참고 있었는데 레드햇 계열은 sysconfig 에 다 있던걸로 기억하거든요 

간단히 되네요

Description: Internet TCP redirection server

 rinetd redirects TCP connections from one IP address and port to another,

 with basic IP-based access control.

 .

 rinetd is a single-process server which handles any number of connections

 to the address/port pairs specified in the file /etc/rinetd.conf. Since

 rinetd runs as a single process using nonblocking I/O, it is able to

 redirect a large number of connections without a severe impact on the

 machine. This makes it practical to run services on machines inside an IP

 masquerading firewall.
