I have an issue and i require advice.
I have a site (Site-1) which has IP address series of 192.168.0.x.
And another site (Site-2) whcih has series of 192.168.2.x
Both sites are connected via UBNT wireless equipment. I have seperate internet connection on both sites. Site-1's internet
router is 192.168.0.1 and it is connected to RB750GL (192.168.0.60).
Site-2's internet router is 192.168.2.2 and RB750GL is 192.168.2.1. I am also attaching a picture so that you can have a
better idea. I am able to route between the sites and easily access the computers of either site.
What I want to do is, when the internet connection at site-2 is down, I want the internet of Site-1 to be used at site-2.
What i currently do is, I change the gateway of the PC to RB750's IP (192.168.2.1) and DNS to 192.168.0.1(IP of the router
But this, I have to do manually and there are some devices (such as security DVR) which cannot be changed as easily.
Please correct me if I am wrong, I think I should be able to surf the internet if i have the IP of my PC (at site-2)
192.168.2.30/24, gateway 192.168.2.2, Primary DNS 192.168.2.2 and alternate DNS 192.168.0.1 when the internet at site-2
(192.168.2.2) is down. But If i change the gateway IP to 192.168.2.1 (Mikrotik's IP) I am able to use the internet from
site-1. But i dont think it is a good practice and it causes me problems.
I feel ignorant because I feel that in the past the above situation use to work (with 192.168.2.2 as gateway IP).
I actually have 1 more site connected to this network and I am running RIP v2. At the moment, I dont have any issues in
routing at all. All i require is help in above situation.
Please do advice me what can I do.
