I am trialling ESS 3.0.563 on windows xp sp2 32bit. FW is set up in interactive mode, with no blocking rules present. I enabled logging of FW blocking connections and worms. I run windows 2000 in a vmware virtual machine (Network is "bridged"). I have a VPN (Virtual Private Network) client, but no FW installed on the virtual machine. When I disable the firewall of ESS (on host computer), VPN connection works OK in the virtual machine. When the FW of ESS is set to interactive mode, the VPN software reports that it is unable to connect. I see no popups from ESS, and there are no FW logs created. I conclude that FW blocks some communication withouth popup or logs, which is a Bad Thing. I reviewed the FW settings, but I do not see anything being set to silently block. Any advices on how to let this VPN through without completely disabling the FW?
