I have just recently implemented a MPLS between two sites. Primary site has 192.168.92.xxx as it's IP range while the secondary site is setup with 192.168.200.xxx as it's IP range. Both are using subnet 255.255.255.0.
Primary site has a Firewall / Gateway setup that forwards communication to and from the Internet as needed. We now have another gateway / router in the network that when someone points to 192.168.200.xxx IP addresses we need to forward everthing to. What is the optimal / proper way of doing this within the network?
Do you change the forwarding in the primary gateway or do you do it with DNS somehow?
Thanks in advance.
