Right now I have been asked to add a firewall to our network for our exchange server. We are running Exchange server on a stand alone server that also acts as a secondary dns server for our network. Is there a distro anyone would reccomend? Or is there any applications or services we should use in paticular?
Also what potential complications would there be running a firewall in front of our exchange server/secondary dns server?
Would it be much easier just to run a isa server instead?
Thanks for your help as allways!
