We have a linksys router (WRT54G) on one of our client sides that won't allow access to our NW6 server through VPN. Both IPSec and PPTP VPN passthrough have been enabled, but we can't ping the server after establishing a VPN connection. I am wondering what ports or range of ports need to be opened and forwarded to the workstation in order to resolve this issue. Thanks in advance for any help that is offered.
