[AccessD] OT: Comodo firewall

Is anyone out there using Comodo firewall pro?  I have it, I like it, and I
am actually considering standardizing on it.  OTOH I need to learn more
about it because (for example) when I turn it on to "custom" it prevents the
other SQL Server from seeing the servers running behind that firewall.  I am
just wondering if anyone out there knows how to configure it to allow other
machines inside of my internal network to establish a trusted zone (I know
that it can do that) and what protocols to allow, etc.  Firewalls just have
too many tweaks and I do not understand them well enough to function.
