EoIP Tunnels

RouterOS General
1

We have a Mikrotik router that contains two wireless interfaces one for associating with a Smartbridges APPO and one for Clients to associate to. The interface to the Smartbridge is associated ok and has a good signal strength.

In order to be able to bridge the clients connecting to the second interface through our network we have added an EoIP tunnel back to our edge router and added the client wireless interface along with the EoIP interface to a bridge. The EoIP interface seems to be working OK and our NAT’d clients seem to be working fine.

On our edge router we also have another Bridge which bridges the WAN and LAN interfaces to allow our customers who are using RIPE addresses to be able to passthrough our router , we have added the EoIP tunnel to this bridge also.

However if we try to use a RIPE address to a machine on the other side EoIP tunnel it cannot contact any other IP address other than that of the edge router itself , in other words in cannot get to it’s gateway which is on the other side of the WAN interface.

Does anyone know how to get this traffic flowing , also we cannot ping back over to clients who are on the remote side of the EoIP tunnel.

Here’s a quick Schematic of what we are trying to do.

Mikrotik >>> Smartbridges >>> Mikrotik >>> CPE
Edge Router APPO Bridge

It’s hard to explain this one so if I have been to vague then shout at me and I will provide more details.

if the EoIP tunnel is working, check by arp-cache, then its a layer 3 problem. think of the EoIP tunnel as of an ethernet-cable.

does the bridge interfaces on both sides have ip addresses? the ip address should bind to the bridge, not to the physical interface.

i don’t understand the scenario, perhaps attach a drawing, or send by PM.

(but this is not exactly a wireless issue, it would probably better to continue this thread in the general networking board)

The EoIP Tunnel seems to be working OK as some of the Addresses can pass through and we have a load of entries in the ARP Cache.

I’ve attached a URL to a Diagram to try and explain what we are trying to achieve obviously I have changed the IP Addresses to protect the innocent !

Thanks for your input so far we are desperate to sort this one out.

I do almost this but only to extend PPPoE tunnels out to users and then am able to assign them public IP x.y.z.xxx addresses directly and not using them up on the routers inbetween.

Sorry I can’t be of more help though.

nice drawing;-)
why do you have WAN and LAN interface within the same bridge as the EoIP-tunnel on the edge router? or is it the same on the router to the right, to get a full bridged network?
on the right side, what do client ap mean? are these wireless-to-ethernet bridges/adapters?

we have a quite similar network working.

Yes we are trying to get a fully bridged network.

And Yes Client AP’s are wireless to ethernet bridges , We are using a combination of Smartbridge and Osbridge units.

You say you have quite a similar network working , How in the hell did you get it working because I’m banging my head against the desk with this one !
