I have a MikroTik router 311 configuration. I have 2 WAN connection and I have 2 LAN , Lan1 access internet form wan1 and lan2 access internet form wan2,but ,
the point now icant access server in lan2 form lan 1.
There are several ways how to make LAN1 get to internet only via WAN1 and LAN2 only via WAN2, so without knowing your current configuration, only generic guidelines can be provided. But as manuals are full of generic guidelines, you obviously need a particular advice, which means you have to follow the hint in my automatic signature just below.
