Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

At work we have a firewall between two networks. I was told they opened up the two ports for me but I needed to modify the IPtables to allow packets to go through. I'm not familiar with the correct IPtable for using NAT.

Since I can't give the IP's, I'm going to use made up ones.

Source: 1.1.1.1
Destination: 10.1.10.33 <-> Make sure to use NAT 2.1.10.33 to access from Firewall network
Ports: tcp/22

Not sure if the following makes a difference

1.1.1.1 is an external IP behind a firewall
10.1.10.33 is an internal IP
2.1.10.33 is external IP

Currently, INPUT, FORWARD, OUTPUT are all default to DROP. I'm assuming both servers will need to have a rule to allow this?

Thanks for your help!
