Two separate connections for two separate LANs with one RouterBoard

  1. Disconnect the bridge between etherX-*-local (Interface properties - remove the Master port).
  2. Mark the packets from LAN subnets (e.g. 192.168.10.0/24 a 192.168.20.0/24): 
    /ip firewall mangle add action=mark-routing chain=prerouting \
    new-routing-mark=routing_mark_office src-address=192.168.10.0/24
/ip firewall mangle add action=mark-routing chain=prerouting \
    new-routing-mark=routing_mark_guests src-address=192.168.20.0/24
  3. Set up routing for packets marked with mangle: 
    /ip route add gateway=ether1-wan1 routing-mark=routing_mark_office
/ip route add gateway=ether2-wan2 routing-mark=routing_mark_guests

    Note: Gateway can also be a PPPoE connection (in case of DSL).

  4. Set up masquerade for the second wan interface (assuming that masquerade was set up only for the ether1-wan1).

PPP VPN

  1. PPP > Profile > Add
    1. Name
    2. Local address: local IP of the router
    3. Remote address: pool from which the remote clients will get IP addresses
    4. DNS server: optional?
    5. Protocols > Use Encryption: Yes
  2. PPP > PPTP Server (button)
    1. Enabled
    2. Default profile: our newly created profile
  3. PPP > Secrets
    1. Name: someusername
    2. Password: somepassword
    3. Service: PPTP
    4. Profile: our newly created profile
  4. In Firewall, allow:
    1. 1752/TCP
    2. 47/IP (GRE)
  5. On LAN interface, allow:
    1. ARP: proxy-arp
    2. Note: if bridged, then do this on the bridge instead of LAN interface.
