Hi to all,
I got some trouble while configuring a bridge within 2 lans like the image below:
The servers (both left and right) are RouterBOARDs with RouterOS 5.5
They have 3 interfaces each (specular configuration):
Server1.eth5 bridged with Server2.eth5
Server1.eth6 bridged with Server2.eth6
Server1.eth7 connected to LAN1
Server2.eth7 connected to LAN2
Into LAN1 and LAN2 there are some clients (eg. LAN1.WindowsXP, ip 192.168.10.171 and LAN2.WindowsXP, ip 192.168.10.172)
Bridges are active one at a time. The second bridge is only for backup, then we can imagine that there is only one bridge.
When the bridge is off, Server1.eth7 reaches correctly LAN1.WindowsXP and Server2.eth7 reaches correctly LAN2.WindowsXP (i tried with ping) and vice-versa.
When I activate the bridge (eg. Server1.eth5 with Server2.eth5), both routers reaches correctly each other, but…
- Server1.eth7 doesn’t reach LAN1.WindowsXP anymore and vice-versa
- Server2.eth7 doesn’t reach LAN2.WindowsXP anymore and vice-versa
…then LAN1 and LAN2 are not connected togheter with the bridge.
This is what i need: http://wiki.mikrotik.com/wiki/Transparently_Bridge_two_Networks
I followed the guide but without expected results. Someone can help me?
NOTE (maybe important):
- The entire infrastructure (both WindowsXP machines and both RouterBOARDs) is virtualized with VMware Workstation 7.1.4
- Both RouterBOARDS have 3 virtual network adapters each, that are ethernet adapters, not wireless adapters.
- Server1.eth5 is in the same “Virtual Switch” of Server2.eth5 (vmnet3)
- Server1.eth6 is in the same “Virtual Switch” of Server2.eth6 (vmnet4)
- Server1.eth7 is in the same “Virtual Switch” of LAN1.WindowsXP (vmnet5)
- Servere.eth7 is in the same “Virtual Switch” of LAN2.WindowsXP (vmnet6)
The screenshots of configuration of Server1 and Server2 are linked below:
