How to diagnose connection problems?

Question

VPN

Good morning! There is a remote client that sits behind two NATs and connects to the head office via VPN. At first, the PPTP connection worked for him every other time. I thought that the problem was in the number of NATs, I forwarded the ports - the connection started, but another problem arose - the connection periodically falls off for 10-15 seconds. Tell me what can be connected with and how to diagnose such behavior in order to find a solution?

Answer 1

Probably try another type of VPN. Open VPN for example.
