I have a Drb server and Drb client that work fine when the client is calling from the same net as the server.
When trying to access the server from a client behind a firewall with NAT enabled, problems start : the server tries to resolve the DNS of the client, which cannot work, since the client has an intranet IP.
This makes me beleive that the Drb protocol is not NAT-friendly, and that it cannot work without some sort of proxy, or firewall workaround for a single natted client. Hopefully I'm wrong...
Did anyone use Drb through NAT successfully?
