Im working in a school where administration block and student block are far. So we kept two different server to manage it individually but connected each other with fiber optics to communicate . Both of them have different ip range. 192.168.0.1 with subnet 255.255.255.0 series and 172.168.0.l with subnet 255.255.0.0 series . Now my student block internet is down and I need to access the administration internet to provide for students. Please help me how to manage it

It depends if how advanced your "routers" are. The devices you buy in most consumer stores are really stupid they only support a single lan block and NAT that to just 1 wan IP.

It also depends how you already managed to get these connected. You pretty much should be able to just change the default route on the broken connection to point to the router that has the good internet connection.

Worst case I suppose you could assign the WAN port on the student router a address on the admin network. It would be NAT behind NAT but it would work. You likely should in the router on the student network put in firewall rules to not allow any traffic to the admin subnet.

Then access the admin. Asking how to ask how to access the admin for a school isn't going to get you any help as you may be a student trying to hack it.

If you're an admin, then figure it out. I'm always puzzled on how to answer the "work questions". On one hand, I like to help. On the other, if you're making $50 an hour being an IT person and I'm not getting anything for helping you online, what is my motivation to spend potential hours looking for solutions.
