Free software replacement for Microsoft ISA
We're looking at moving away from ISA and to Threat Management Gateway (, does anyone know of a free software replacement that:

Has a nice GUI that allows us to see what's going on in real time e.g. who has VPN sessions, how long they've been connected, etc.

Is compatible with or has a tool that can convert our ISA firewall config - recreating all those rules from scratch in a new system would be difficult, time consuming and would probably break a lot of things.

Has good logging and alerts

Plays nicely with Active Directory

As for replacements, it mostly depends on your needs.
