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

[w201]

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!

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.

That did it, mint-me. You're a rockstar

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!
