MikroTik

Hello All

Apologies if I have posted this in the wrong forum. Please move it if necessary.

My query is complex for me.

I am trying to setup users on two differerent networks to be able to share same server and printer.

Network A has 3x users with their own adsl router and internet.
Network B has 2x wireless users with different adsl router and different internet.
Server and Printer

Both networks need to be able to share server and printer and still have their own independent internet access through their own adsl routers.

I have a 450 Routerboard and a Dlink 16 port Layer 2 switch.

I have been fiddling with Vlans and routerboard, but cannot seem to be able to get 2x independant gateways on Mikrotik functional and still be able to get traffic routing A and/or B to the shared resources.



Internet A ===> Adsl A ===> Mikrotik 1 ===> Switch 1===> Users A
Mikrotik 1 ===> Switch 1 ====> Shared server and printer
Internet B ===> Adsl B ===> Mikrotik 1
Users B connected to adsl wireless and need access to Server and Printer, but must use Internet B.

Can someone advise how to configure?

Thanks in advance
