I have the following setup:
MY-PC: eth1: 192.168.1.1 - - - 192.168.1.2 :eth0 :SERVER: eth1: 192.168.2.2
My SERVER can be used as a router and is not restricted by
(No restrictions in the forwarding table.)
eth0 on the SERVER is only accessible on TCP port 80.
iptables -A INPUT -p tcp --dport 80 -i eth0 -j ACCEPT
eth1 on the SERVER is only accessible on TCP port 22.
iptables -A INPUT -p tcp --dport 22 -i eth1 -j ACCEPT
If I now try to access 192.168.2.2 (eth1) on port 22 from MY-PC, I can't connect.
A similar question is answered with answer 4 of this post, but the scenario happens on the local machine only.
Is it possible to access 192.168.2.2 (eth1) on port 22 on the SERVER even if 192.168.1.2 (eth0) only allows traffic on port 80?
