Yeah, it's a double-edged sword -- some firewalls are far more advanced and configurable than others (why Sygate and Kerio are far superior to ZA, for example), while at the same time those firewalls make it easier for you to lock yourself out of your own trusted connections if you're not careful -- if you're a bit of a novice like myself, that is, me being the AO Village Idiot and all (hmm...if I hadn't already claimed "AO Autobot" that might make a good title ). The slightest misconfiguration can cause such a problem (as I showed in my Sygate thread), but a little patience and willingness to learn the ins and outs will go a long way.

Anyway, I'm starting to wander off topic...Just thought I'd throw that in there.
