2x 3100 back to back setup was created by elybis
Hello folks!


I want to setup a connection to a remote office via a leased copper line with 2x Vigor 3100:

Code:
10.50.14.32/27 Remote Office 10.50.13.0/24 Headquarters -+------------ ------------+ | copper wires | +-- VIGOR3100 ==================== VIGOR3100 --+-------- MAIN GATEWAY 10.50.14.33 10.50.13.28 10.50.13.29

I want the traffic to be fully routed from 10.50.14.32/27 to 10.50.13.0/24 and vice-versa. However, I keep having problems with the configuration of the 2 WAN interfaces. I can successfully set up an SDSL link but my traffic does not get routed in any way.

I have set up the DSL configuration in the remote office to "CPE" and in the HQ to "CO".

Then I've tried various setups of the WAN interfaces:

1) MPoA Enabled, Bridged IP, bridging off, static IP
Result: successfull SDSL connection and Vigor1 can successfully ping static WAN IP of Vigor2 but not internal IP of Vigor2

2) http://www.draytek.com/user/SupportFAQDetail.php?ID=270 (Back to back VPN)
Result: Routing works in both directions. But I can't get any further than 10.50.13.0/24 from the remote office - I want to have traffic from the remote office with a destination other than the HQ (e.g. internet) to route through the main GW in the HQ 10.50.13.29

3) MPoA Enabled, Routed IP, bridging off, static IP
Result: does not work, no traffic gets routed


Please help me with setting up the WAN configuration :-) Any hints would be greatly appreciated!
