Dear community,

I bought a TP-Link Archer VR900 to replace my actual 4g Router. 
I have a small business and i used a 4g router. The business nearby offered my there line because they have fiber and its more reliable than my 4g.

They use the IP gateway 192.168.1.1 and my network is in 192.168.0.258 and i want keep that. I dont want so change all settings in my network again.

how i have to setup my router, to have on the WAN and in the LAN different IPs? Sorry im not really familiar with network configurations.
