I just replaced a 3Com VPN router with this Linksys unit since the 3Com unit constantly locked up with incoming Teamspeak/Ventrilo traffic. I always used my Pocket PC (WM5) to VPN into my network and view Slingplayer or a network camera. The RVS4000 doesn't support PPTP, so I'm trying to figure out how to connect with IPSec. It seems that connection, being more secure, requires a certificate? If that's true, how do I go about setting up the cert on the PocketPC so it can connect with the RVS4000?
