A decent firewall for ubuntu 9.10 server?

[Spooter]

Hi all,

Im running some web and email services on my ubuntu 9.10 server. Could you recommend a good firewall so I can lock down all access other than the incoming\outgoing ports required for web and email.

Possibly one I can manage via a web gui would be good. Or even better using webmin?

Thanks again.

I think IPTables is the standard for configuring the firewall for Linux.

I use Shorewall for configuring it, as it seems much easier. There is a webmin module for it. That said, it's really easy to configure Shorewall from the command line anyway.

Cheers john,

just installed and configured.

Nice and simple.

Just going to install the webmin module now
