I have a setup of two sites both with Microtik RouterBoard 750.
Site A has the following Setup
ETH1 with 2VLANs (VLAN 1 = Internal Netwrok 192.168.7.1/16, VLAN 2 = Guest Network 192.169.5.1/24)
ETH2 = Connected to Fibre Modem that connects to Site B Directly
ETH3 = Public Intenet Modem
Site B
ETH1 with 2VLANs (VLAN 1 = Internal Netwrok 192.168.11.1/16, VLAN 2 = Guest Network 192.169.4.1/24)
ETH2 = Connected to Fibre Modem that connects to Site A Directly
ETH3 = Public Intenet Modem
My problem is that when i do not use VLANs on ETH 1 i can connect to SITE B from SITE A and vice versa, but when i activate VLANs i no longer can connect to the Remote Sites.
When you make a VLAN, you are creating a new virtual interface that talks on that vlan on it’s source interface. if you want to bridge VLAN traffic from site 1 to site 2, you need to create VLAN2 on ETH1 (lets call this V2-E1) then make another VLAN2 interface on ETH2 (V2-E2). Then go in and make a new bridge (br-V2) and add both VLAN ports (V2-E1, V2-E2).
If you are able to talk to the internal network off just ETH1 interface, then VLAN1 is not tagged, so you can just use port ETH1 as the port for communicating to it.
If that doesn’t do it, make a quick diagram of what you are trying to achieve and I will see how I can help.
