In my setup, I have a security gateway in a main location which handles all the remote VPN access connections. I also have a satellite office that has a security gateway that has multiple VLANs connected to it. While the administrative VLAN has site-to-site VPN defined to the main location security gateway, the other VLANs are not part of the site-to-site VPN. When users in the other VLANs try to use the Windows Capsule client to do Remote Access VPN, they get "Connection Failed: Certificate not valid" error. We use certificate based authentication. If the same users try this from any other internet connection (including their mobile hotspots), everything works fine. What could be wrong?
Any clue will greatly help.
Thanks in advance,
Krishna
