This has me beat.
The problem is the same for RV042 and for professional Cisco vpn routers.
I only have this problem when I use my Windows 7 laptop, which has 64 bit professional installed.
What I can do:
- I can login to all vpn's using a vpn client (QuickVPN 1.4.1.2 and VPN Client 5.0.07.0290) from a fixed network and I can ping devices
- I can login to all vpn's using a vpn client (QuickVPN 1.4.1.2 and VPN Client 5.0.07.0290) using Blackberry modem and I can ping devices
- I can login to all vpn's using a vpn client (QuickVPN 1.4.1.2 and VPN Client 5.0.07.0290) using WiFi but I cannot ping devices
So only if a login using a WiFi with my Windows 7 64 bit professional laptop, I cannot ping any device within the vpn (I tried with W 7 32 bit and XP, all ok).
I have tried from WiFi's that use DLink and Belkin routers and in different countries.
