Use two routers, A connected to the education network and B connected to the telecommunication network. Route a is set to 192. 168. 1, and route b is set to192.438+068.1.254, so you can choose the gateway on your computer when accessing the education network. The gateway to the telecommunication network is set to192.168.1.254, and two ordinary routes are enough.

The other is to connect two lines to a routing or proxy server device that supports dual extranets at the same time. When a machine in the local area network accesses an external network, the device automatically judges and selects the best external network exit according to the relevant network settings, so that the internal network client can obtain the best network speed. But this requires the purchase of dual WAN routing or proxy servers.
