I have a new client with the following
And they have set all of the subnets to 255.255.0.0 or 255.0.0.0 ( will confirm) so "all of them can see each other"
( they have an existing internet vendor that is providing a router at each building and is allowing them access across the internet.)
But they have not been happy with them and I am helping them configure new SonicWall VPNs with new Cable modems to a new cable company
I always have set my Sonicwall LAN ports with 255.255.255.0 and then the Site to Site VPN's handled the traffic very nicely for other businesses ( I must admit little knowledge on subnetting)
We are testing the new SonicWalls on a limited basis on all three buildings ( since we are in a live production enviroment)
If the client cannot change all their PCs from 255.255.0.0 should I change my SonicWall LAN to match ?
