Hi,
Does someone have experience with SD-RED Failover via LTE which is provided by the Deutsche Telekom.
We have a customer who has a couple of SD-Reds in Place, which are connected via a dark fibre backbone. Some of them have a dsl backup which is working.
In one place there is a AVM Fritzbox 6890 and the red is configured as an exposed Host. In this scenario the Red cannot establish the tunnel connection.
The Red cannot pass phase 2 (router). Which doesnt make sense because I can see the connection in the TCP DUMP on the XG Firewall.
I know that LTE in generell is working because we deployed some of them with an LTE Route in the first place. The only difference is that we didn´t use a fritzbox and deutsche Telekom in the deployment phase.
Regard´s
Silvio
