Ubuntu Server Firewall not opening port
I am trying to open port 25 using ufw, and but the port remains closed. I am able to telnet to the Postfix server locally, but cannot do it from my computer. I also ran a scan and port 25 did not show up as an active port.
Code:
PORT STATE SERVICE |
So what command did you try using? Please explain your steps otherwise it takes longer to resolve issues, because right now it would be a stab in te dark with a typical response like read the manual and run the command properly checking for spelling mistakes
Code:
sudo ufw allow 25 |
I added it using
Code:
sudo ufw allow 25 Code:
Skipping adding existing rule Code:
iptables -L Code:
Chain INPUT (policy DROP) |
Can you see the rule mentioning the port specifically in the iptables configuration file?
|
Maybe also just try to ensure that traffic can actually get out.
Code:
sudo ufw allow out 25 Code:
telnet ip.add.of.server 25 |
Is postfix listening on that interface?
