Occasional Visitor
I have an ASUS RT-N66U (Client) and an ASUS AC88U (Server). Both are running 380.65_2. After upgrading to that specific version on the client and leaving the server at ~380.64, I noticed that there were issues were the client would would say that it was still connected to the VPN but any attempt at trying to ping 10.10.10.254 (network on the server side) would state "Request timed out." This happens on multiple devices and not just one.

It isn't specific to just that one IP Address, if I try to connect to the Server using it's IP address, it also fails with the the inability to ping or connect to the router's webserver. In the system log. all I see are a Packet Drops (because I have a high filter for NAT/Firewall packet logging - I have disabled it to diagnose for the next day). The below stuff is when it doesn't work.

After turning the VPN client off, and then on again, I am able to ping and receive responses from across the VPN - same with connecting to the server.

Would really appreciate some help, as this is super broken, and I don't want to have to setup the VPN again.
 
Actually not shortly after posting this thread, it failed again after flipping the service off and on, and using ping to test connectivity.

After ~7 minutes it stopped responding again.
