Fhillip, could you perhaps give us more information on how your networks are connected to each other. A network diagram is preferred.
Usually a "network" refers to more than just 1 IP address, instead its an IP address range like 172.30.8.0 - 172.30.8.255 (written in CIDR notation it would be: 172.30.8.0/24).
Can you ping devices on both network A and network B with the Ping tool from within Winbox? Once you can ping devices from the router, then you can proceed setting up the routing/NAT (masquerading) on the router.
For the networks to be able to access each other, they both have to use the MikroTik as the gateway OR the gateway that they're currently using should have a static route pointing to the MikroTik if the destination network is the other network.
eg.
- Setup:
- Network "A" (10.200.221.0/24) is connected to the MikroTik eth0 and their gateways all point to 10.200.221.1 (which is the IP address on the MikroTik eth0).
- Network "B" (172.30.8.0/24) is connected to an Access Point set up as a router with the IP address of 172.30.8.1. Again, all the devices on this network have their gateway set to 172.30.8.1.
- The Access Point is connected to the MikroTik on eth1, with eth1 having an IP address of 172.30.8.2
For this setup to work, you'll have to:- add a static route on the Access Point such that all traffic destined for network "A" (route with dst-address=10.200.221.0/24) must go through the 172.30.8.2 gateway
- Add a static route on the MikroTik such that all traffic destined for network "B" (route with dst-address=172.30.8.0/24) must go through the 172.30.8.1 gateway
