[SOLVED] Help Me Configure My Firewall to Accept SSH...

Postby w201 on Fri Jan 25, 2013 10:10 pm

Hey everyone,

I can't seem to ssh into my mint machine from another linux machine, unless I turn off my firewall.

With the firewall active, If I go to administration >firewall configuration and add rules to allow ssh connections through port 22 from a LAN address to another LAN address, it still doesn't work. Any of you guys know how to set this up so I can ssh without having to turn off my firewall?

Thanks a bunch!

Linux Mint is funded by ads and donations.

I assume you are using gufw/ufw.

Set the top drop-down, Incoming -> Allow
this will allow all incoming connections.

Allow ftp connection first, add rule from "Advanced" tab:
Allow > In > Both
From: IP [Client]
To: IP [Server] Port [22]

Then block all other incoming, add rules from "Simple" tab:
Deny > In > TCP 1:65535
Deny > In > UDP 1:65535

That should do it.

Glad to be of help, w201.

The way you are doing it (SSH) is also my favorite, and most secure way to connect on the network.

Enjoy!
