how to open port so other vps can connect thru that port?

| Hi,
I have two vps, vps1 and vps2. vps1 needs to connect to vps2 thru port 2222. So what I did in vps2 was, to run the following command:
iptables -A INPUT -p tcp -i eth0 --dport 2222 -j ACCEPT
iptables -A INPUT -p udp -i eth0 --dport 2222 -j ACCEPT
I have also tried:
iptables -A INPUT -p udp --dport 2222 -j ACCEPT
iptables -A INPUT -p tcp --dport 2222 -j ACCEPT
iptables -A OUTPUT -p tcp --dport 2222 -j ACCEPT
iptables -A OUTPUT -p udp --dport 2222 -j ACCEPT
service iptables save
service iptables restart
but when I use vps1 to do:
telnet vps2ipaddress 2222
I got the connection refused problem.

| I presume that this doesn't happen when iptables is stopped?

| I still got the same connection refused error
when I run service iptables stop on vps2
then run the telnet command on vps1

| Did you edit the sshd_config and change the port?

| By default ssh is port 22 if you don't tell the ssh service it won't run on a different port.

| Try adding the IP addresses of both VPS in firewall allowed list vice versa and then have a try.
iptables -A INPUT -s VPS IP address -j ACCEPT

| Hello,
Make sure the IP address is in allowed list of the firewall.
Also if you are trying to connect from one vps to other vps via ssh using a different port it should be updated in the sshd config file.
