Hi, good Afternoon…
Today a client asked me to make a big modification on his internal network.
The client has 5 branch offices all interconected with Wireless links.
At the time there is all a big net in 192.168.2.x/24 subnet… In 4 of the 5 branch offices the client has DSL Modems, but only one of them has DHCP activated. But all all the time there are IP conflicts.
The idea is to sepparate all the nets, with their modems, without losing the ip contact… For example from net of eth1 have full access to an ip camera installed on eth3…
All like this Image:

Each net with his corresponding DHCP activated, but the worst thing is that the client wants that, when he changes the gateway ip of his computer, he could use the internet connection trought the DSL Modem of one of the Other 3 Branch Offices. I think it can be made by generating various ips on each RB750 ethernet port, and routing looking for the dst-address in nat.
I am now with a terrible big headache haha i don’t know how to solve this, neither if it is possible or not…
Could you help me Please?
Thanks
