Hi.. my situation is: we have 2 subnets (172.16.0.1/20 & 172.16.16.1/20) with their respective gateway routers.. (ubiquiti edgerouter lite on both). Both networks are working as they should (just re-addressed both subnets yesterday to allow more leases). My goal is to route between these two networks to allow continuity throughout the school as we have static printers and a Server (DC) that would be nice to be able to connect to no matter which subnet they are on, they can utilize. On both of the edgerouter lites there is a 3rd ethernet port that could possibly be utilized to achieve this goal, but not sure.. I have read some scenarios that say to use a 3rd router to enable this functionality. I am not opposed to Re-Address these networks again if that needs to happen. If possible I would like to utilize the Server for DHCP & DNS, but think this isn't going to happen.. but not sure if adding a 2nd Network card could make it work properly. I know this is alot.. I appreciate any responses. - Bill
After that, to have both the bandwidth of both routers, you need to add a DUAL WAN router before it (the whole LAN connects to this DUAL WAN router, and the router connects to the two working routers).
