I have an issue where I use Cisco AnyConnect to connect to a remote environment hosted by a customer of my business. Several months ago, while connected on this VPN, I started getting incidents where I would lose my internet connection on the VPN, and thus my connection to a remote server in my customer's environment would get terminated. Note that the internet connection to my PC worked ok, it was just the VPN that was the problem. When this happens, the problem is fixed by disconnecting and then reconnecting to the VPN. There are also occasions where if I leave it long enough, internet connectivity on the VPN will be restored, but usually I don't bother waiting for this to happen.
These incidents often happen many times a day, and become a real productivity blocker. I figured out that this would happen when there was a short break in internet connectivity to my PC, usually from wifi coverage that was a bit spotty (the kind of thing that makes a video call freeze up for a second, then recover). It would also happen if I was using wired internet, then disconnected from it, and internet stopped for a moment while I automatically connected to a wifi network.
I wonder if the source of this issue is some timeout setting that needs to be extended, but unfortunately I'm not able to see what configuration options are available, as the customer is in control of this (as well as other things, like a firewall). I understand that when you stop sending packets through the VPN for too long, the connection will be broken, but I don't think that's my problem here, because the time that my wifi connection is lost is too short, and AnyConnect indicates that I'm still connected, I just can't access the internet anymore while I'm connected.
Are there any suggestions that I can use or suggest to the customer so that we can troubleshoot this together? Like I said, I only have access to a limited number of settings, and need to collaborate with administrators to change anything else.
