VPN Connection Loss (Intermittent) AWS VPC VPN
Hello Community, this has been a long lasting issue for my company and I. We recently migrated to AWS and have a VPN IPSEC Site-to-Site VPN running in Main Mode between Amazon and our Sonicwall TZ100 (Running OS 18.104.22.168). The connection can be up and stable for days and then it just drops. It doesn't drop completely as the TZ100 shows the tunnels up and AWS also shows the tunnels up. Data just flat out stops flowing. To fix this I usually disable the connections and enable them to force them to reauth with each other. I am seeing other folks with different routers and different vpn setups all having the same issue and no resolution is to be found. Any help to get be going in the right direction would be great. Sonicwall probes don't work well because they want to disable the route all together if the connection fails. Powershell scripts keeping interesting (ICMP) traffic flowing over the VPN don't work. Running non-assym doesn't work. Log files and configs show it's not the Sonicwall, and AWS is showing similar results. Any ideas Comcast?
