Hello Markus, another idea: the dmq module supports multiple destinations, so you could enter a internal and public IP adress into a A record, and then let dmq connect to both. But the actual routing descision is (currently) done on a linux network layer level.

Some ideas with iproute2: - setup a default route to the public internet - setup a more specific route for the dmq endpoint - configure a timeout to detect if one gateway is down to deactivate the route Another idea would be to enter a DNS record as dmq endpoint and then change it with a monitoring trigger event. Not 100% sure how dmq refresh this, will need some testing.

In my test setup have 2 Kamailio servers in 2 different data centers. The data centers are interconnected by a crosslink. Each Kamailio server has configured an internal (private) and an external (public) IP address. The internal IPs are routed to use the crosslink. The external IPs are routed through the public internet by different ISPs. The requirement is that the replication should primarily be routed via the crosslink, only if the crosslink is down it should be routed via public internet. As I understand the „server_address“ parameter can have only one IP address. If I configure the public IPs on both sides and one ISP connection gets disconnected, packets will NOT be routed automatically via the crosslink. And the other way around, if I configure the private IPs on both sides and the crosslink gets disconnected, packets will NOT be routed automatically via public internet. Is there any way to setup and use dmq for such a scenario ? Thanks and regards Markus -- Henning Westerholt - https://skalatan.de/blog/ Kamailio services - https://skalatan.de/services
