I have a home office trying to VPN pass-through to a Sonicwall router at company HQ. The user (my wife) then Remote Desktops to her system at the office.
She can connect with Sonicwall, and even connect with MSTSC, but she regularly will lose the connection. It has been incredibly frustrating.
We have upgraded the desktop from Vista to Win7.
We've upgraded the Sonicwall from 4.2.6 to 4.6.4.
I've removed the Cisco Valet router from the home setup - and direct connected to the cable modem. Wow - that works great, but now no one in the house can connect!
This seems to point to the Cisco Router as having problems.
I'm happy to provide more information to anyone interested in helping out.
I'm wondering if I need to configure some items on the Router to force TCP hold or something like that.
