We have a VPN from our ASA to a SonicWall in a remote country. The SonicWall is managed be a 3rd party. It seems only the remote site can bring the IPsec tunnels up. I can see the VPN is up but with 0 Tx and 0 Rx, if I ping the remote subnet from the ASA side the transmit goes up, but to the Rx. If they ping our subnet the subnets seems to spring to life.
Is there a setting they need to look at for initiating the tunnel, or any commands I can run my end to see what is happening?
