Ports closed

[markenic]

Hi! A have an MTA server on Ubuntu os, and some days ago it worked fine, but now I can't connect becouse the 22126 and the 22003 ports are closed. I tried without firewall, it didn't work. I allowed the ports.

 

Can somebody help me with that?

Hi,

Have you unlocked them from iptables?

iptables -I INPUT -p tcp --dport 22005 -j ACCEPT
iptables -I INPUT -p udp -m multiport --dports 22126,22003 -j ACCEPT

This should hit fine.. It's what I do on my end to fix.
