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?
