I have a problem with a site to site VPN tunnel.
I have setup a tunnel with a remote site (188.8.131.52/16) to my site (10.212.0.0/16 10.147.108.0/24). The remote site can initiate Phase 2 but does not get a ping response.
Phase 2 is not even attempted when the local site pings a server on the remote site. Please could someone help resolve the problem or advise how I can troubleshoot the connection? How can I monitor traffic in the VPN tunnel?
