Hi there, I've just begun using Cisco VPN client ver.4.7 and it's no problem except when I'm behind my Linksys WRT300n v2(2.00.16), I have also tried 2.00.13. All three VPN passtrough types are ENABLED. As wireless network adapter I'm using WPC300n. My PC is a Dell Latitude D800. The build in wireless network adapter is disabled. If I hard-wire the PC to the WRT300n the problem is still there, but if I go direct to DSL modem everything works OK. Anyone having a good idea??
