I have 2 internet connections at home. I surf on both of them: every other connection switches isp.
I already use my VPS as a regular proxy for surfing, ensuring me I always have the same IP address for certain sites.
However: I can not use a proxy for a certain Usenet program, so I would like to set up a port on my VPS as a very specific proxy. How do I do that?
I've tried this rule:
iptables -A FORWARD -p tcp -i eth1 -o eth1 -d 256.256.256.256 --dport 563 -m state --state NEW -j ACCEPT ACCEPT tcp -- anywhere usenet-server.com tcp dpt:nntps state NEW ACCEPT udp -- anywhere usenet-server.com udp dpt:nntps state NEW
But they do not work.
