We are trying to set up a centralised hotspot server, where the CPEs connect to the server over a 3G network via L2TP tunnels. At present a test tunnel terminates correctly onto a bridge (loopback), but we see no traffic on the bridge, only on the tunnel.
The hotspot server is running on the bridge and the hotspot IP is assigned to the bridge. A laptop connected to the CPE can browse websites freely but is never redirected to the hotspot login page due to the fact that the traffic never traverses the bridge.
We already have a different hotspot running on the same Mikrotik server which works, but the L2TP tunnels are terminated outside of the Mikrotik on a Cisco router.
For the new set up, we need a fully closed system so we need everything to go through Mikrotik. How can we make the traffic from the L2TP tunnel traverse the bridge?
We were informed by Mikrotik support that it is not possible to provide hotspot service on an L2TP interface in this manner. We will have to acquire a BRAS to terminate the L2TP tunnel and bridge each tunnelled PPP session to an individual VLAN to be terminated into the hotspot controller. Since there are other hotspot controllers out there with more comprehensive features, unfortunately we may have to move away from Mikrotik for this application.
Sorry to rake up an old post
This is possible tested and working
Currently only tested on MT AP, but we are increasing AP and following APs will be tested in next 2 days:
- BelAir Ericsson
- Aruba
- Cambium
- UniFi UAPs
in case you need some radio to test we can setup a test environment for your APs also
I am trying to do this but have been unable to…
Can you share a conf of this working?
ok, I dont have a running configuration anywhere but I can guide you, follow the process:
- Set up BCP, to bridge the tunnel,
- Run hotspot on this bridge interface
Let me know if you run into any problem
