Topic: firewall on SME server

[penguin]

Hopefully someone can help me out here... Just gimme a break coz im new at this!

Ive installed SME Server 6.0.1 and its working like a bomb. I have it hooked up to a ADSL line, so its acting as the gateway and Mail Server. I dont have any kind of protection (firewall). How do I g about installing a firewall on my SME Server. I did a search on this site, but I didnt find a HOWTO guide??

Thanks a lot

So far, im very impressed with this SME Server!

If you configured it as a Server & Gateway then the firewall is already running.
I think you need to read some documentation, ie RTFM

also look at the contribs.org Documentation link

If you're a linux noob like me, it wont help you too much since you still have to understand iptables.  but at least it lets you see something, rather than command line.


Good luck.

No - lets not confuse anyone. You dont need to install anything. The server comes with a firewall out of the box.

Hi,

  With that RPM can i see someone trying to hack our server.? I'm new to linux so it's handy if i can see any unauthorized access atempts.

So we don't need any firewall if we install SME as a Server and gateway?

In Server & Gateway mode the firewall is automatically installed and configured.
No user configuration is required.
The appropriate ports are opened (and/or closed) when the server is initially configured using the Configure server panel and also when changes are made using server manager.

You don't have to directly configure firewall (iptables) rules unless you have a particular reason ie you wish to do something that is not catered for in the server manager or configuration screens.

This concept applies to all the settings in a sme server, make the changes you require in server manager and the behind the scenes conf files are updated automatically.

Makes it very easy to use.

Of course it is totally configurable using command line if that's what you need to do, but you should do these type of changes using custom templates, keeping in mind the way the templating system works to update the conf files.

Ok cool! Ive done a LOT of reading, and im learning a lot! I really take my hat off to the people running this site, they have done a really good job! Looking forward to implementing a lot of the stuff I have learnt...so thanks to everyone that has posted reply's to my topic!

One question... What is the point of installing this PRM file? I take it, it only needed if I want some kind of interface for the firewall. Coz Im DEFINITELY NOT able to manage it in the command line...

There is no point installing it for you. One only needs it if default interface (transparently configuring firewall rules on the background) doesn't accomplish some specific, nonstandard rules.

Yeh, i installed the rpm, but its pretty much useless, everything is setup nicely.  I like having it in my menu though...
