I am trying to configure a site to site VPN between TZ170 and SonicWALL 2600. The problem I am having is that when I go to configure the TZ170 it keeps dropping the LAN connection.
I have to unplug and plug back in the router in order to get back the LAN connection. But it only last for about 30 seconds before it drops again. I have a continuous ping going on my console computer to see when it drops and it like clock work after 30 seconds I have to unplug again. What could be causing this to happen.
I have the TZ170 connected to a Comcast router LAN on port #1 and my console computer is plugged into port #2 and I am connected to port #1 on the TZ170. I am able to get to the SonicWALL config page but by the time I navigate to the VPN page to configure connection drops.
