Hi Guys,

Our organisation has just had UFB installed which is great, except the PPPoe connection requires a VLAN tag of 10.

Our Netgear UTM9s does not support VLAN tagging on the WAN interface.

So I purchased a Mikrotik RB750 which I thought could do the tagging for me.

However I have no idea how to get the UTM9s' WAN port to talk to the Mikrotik. I can get the Mikrotik to connect to the ISP via PPPoe, But what I really need from the Mikrotik is to just out bound tagging allowing the UTM9s do the PPPoe connection.

Any assistance would be greatly appreciated.

Thanks

You simply create a VLAN10 on the interface you're using for WAN and then use the VLAN10 as your external interface.

Thanks for your speedy reply.

I think I understand what your saying. I have created on the Mikrotik VLAN10 on eth0(default WAN port) and assigned VLAN10 my static IP.

The bit I dont understand is getting the UTM9s' WAN2 port to talk to the eth1 port on the Mikrotik - I see no traffic on the eth1 interface.

Do I need to NAT, Port forward, etc

Thanks again for the help.

You can do it a couple of ways..

You can create a bridge interface and link the VLAN 10 on the Tagged Port 1 with the Untagged Port 2

See: http://ferdi.blog.unas.ac.id/pengenalan-dasar/transparent-bridge-with-mikrotik/ (its not the same but you'll get the idea)

or you can do it in the Switch config of the router.

See: http://wiki.mikrotik.com/wiki/Manual:Switch_Chip_Features

Again thanks for the speedy reply.

If I was to go with the bridging option I believe my config would look something like,

interface bridge add name=bridge1 disabled=no arp=enabled - in order to create a bridge
interface bridge port set ether0 bridge=bridge1 priority=128 path-cost=10 - To add the physical eth0(WAN cable from UFB) interface to the bridge.
interface bridge port set ether2 bridge=bridge1 priority=128 path-cost=10 - to add the physical eth1(Cable connecting UTM9s and Mikrotik) to the bridge.
interface bridge port set VLAN10 bridge=bridge1 priority=128 path-cost=10 - to add the VLAN interface (required tagging) to the bridge.

Does this look correct?

Is there maybe a better way?

You won't want the port with the VLAN also included in the bridge - this will fail (can't bridge both together)

You just want to bridge the VLAN and the port used for the connecton to the other router.

Hi oktobot,

How did it go with your bridge setup. I have the exact setup as yours, using a UTM9s now trying to connect to UFB. Getting myself a RB750 for bridge setup as well. Just want to know did you got your working? If so, what was your final configuration? 




Thanks.

Is that mikrotik model cheaper than a layer2 switch?
