Router Hide all the 192
I had an AC1200 Router to brought in Unifi Connection.
LAN Port 1Connection were attached to FORTINET Device to Link Connection to Out of Country running on 10.xx.xx.xx
LAN Port 2Connection to CISCO Router in Order to distribute the 192 and 10 connection to all of the Employee in the organization
10.xx.xx.xx was on a FIXED IP
192.168.0.1 was on Dynamic IP
When I connect another Router the Archer AX20
I set it as AP Access Mode
In withn 10 minute time, the entire organization will be in 10.xx.xx.xx
then the 192.xx.xx.xx will be hidden and gone
If I would like to get back the 192.168 environment, I had to turn off the Archer AX20.
May I know what can I do to overcome this issue?
