[Klug-general] Firewalls

[Peter Childs]

I need some advise.

I have a rather complicated LAN that has two (yes 2) Network Address
Translations (NATs) between it and the internet at large.

1. Is a ADSL Be Box that I've got very little control over
2. A Linux Box that runs IPTables and Squid to Cache and Virus scan
the web (the rules don't add up to much more than that, (Oh it also
have a VNC access)

I want to be able to run VoIP on the network to communicate.

I need a Nat as I have about 30 Linux PCs connected and 5 or 6 Windows
boxes but I don't think I really need two...

Any ideas.


Peter.
