Is one of the VPN endpoints behind a NAT? You might need to configure your gateway/router in bridge mode to bypass NAT before it gets to your MX.

Are there any known issues for the internet connection at either end? I have a lot of VPN drops at one of my sites, but that internet connection is wireless and not reliable.

I am in midst of converting several sites to Meraki s2s and 5 sites in; i have this happeneing every 2-5 minutes since-turn-up last week. No noticeable (reported) impact to users...but don’t like it.  I’m Thinking about looking at the circuit first?

Hi to all,

I´m also noticing that "problem" in one of my networks but till now I could`nt find a problem on the physical lines or cpe-routers 😞

could probably the NAT- which is done on a 3rd Party Firewall before the 1-armed-concentrator be the problem? if so, what`s the best way I can troubeshoot that?
