How to create Virtual LAN?

[nova-nuker]

Here is the situation: I run a gaming zone and I've 2 branches of it. I've developed a socket server-client program to monitor the customers' login timing and accounting. In both the branches I've internet from same ISP and I get one static IP from ISP in each branch, which I share on internal LAN through router. My software runs locally that means in each branch of my gaming zone I've a server.
Now I want this to be monitored centrally that means single server and single database managing all client PCs in all branches.

How do I do this?

At least you need a proxy as bridge between 2 branches. Since your branches
just have 1 IP for each, then it will be impossible if proxy doesn't have public
IP. My suggestion is, request one more public IP from your ISP or install
the proxy server into one of router.

ya I'll try to get one more static IP then. Thanx.

But I thought there must be some other solution like creating virtual lan.
Because, we use gg e-sports platform and we play games with other players as if we are on same lan. I know HAMACHI but its kinda slow.
Can anyone suggest possible solutions.
