Operating Systems Linux Ubuntu Connecting to a remote server Post 302279274 by linuxjunkie on Thursday 22nd of January 2009 09:37:09 AM

Your router has got a build in firewall.
The firewall is set to allow connections from a pc on the local network to another pc on the local network. ( This is called forwarding ).


By default your ip firewall is set to deny incomming connections to your local network on some ports. the default ports are thos that are used by windows to connect to shared drives.

This is a very important security feature, if you disable these ports or allow traffic on these ports any one on the internet will be able to access your server if the find your public ip address.

Now if you had mail server on your local network and you wanted people to send mail to it on port 25 (SMTP) then you would set a rule in your firewall to allow incomming traffic on port 25 and to forward it to the internal mail server.

So you sepcify what port you allow traffic on and you specify that it can only go to one specific ip address.

Hope this helped
