NATting traffic with a 3rd party VPN peer due to subnet overlap

Hello, I'm new-ish to the MX routers. We need to create a VPN between our MX and a non-Meraki router. Our subnet is 192.168.0.0/22. I was told by the 3rd party that our networks overlap (apparently they se the same subnet) so they asked if we could NET our traffic to a different IP subnet. In looking at the 3rd party VPN peer setup, I can't figure out a way to do this.   Is this done on the Site to Site VPN config screen or somewhere else? Can it be done at all?   Thanks! ... View more

Thank you! This will be done after hours, so downtime will not be a factor. This makes the job much easier. ... View more

Changing the subnet mask - what will happen to the VPN

I am new to Meraki.   We have two locations connected with a site to site VPN , MX's on both sides. The HQ side has a subnet of /22 and the remote is /24 on its LAN. I need to change the subnet mask at the remote site to /22 to add more subnets. I would also like to change the gateway IP to .1, it is currently .250   What will happen to the VPN if I change the subnet mask and the gateway IP? Will I have to reconfigure it, or will it see the changes and adjust on its own?   Thanks!     ... View more
