Revlets and firewalls

[Luis]

Hiya,

Ah, ok: If you can create an exception for the executable in the  
firewall application, then that should be ok. It's not what I would  
do as standard practice as an app can misbehave, so you're giving it  
full net access.

In this instance I'd look for the revlet executable to exclude, not  
the 'app' itself.

Cheers,

Luis.
