I think it's called "Dynamic interface resolving" in the GUI and mine was set to "static interface resolving" by default. SecureClient tries to locate the gateway by sending these RDP packets (unfortunately, RDP is the same name as what Microsoft calls Remote Desktop Protocol so I always get them confused in the logs).

Otherwise it tries to find the firewall solely by its downloaded topology.

Thanks for that. Not heard of RDP probing before -could you either point me
towards some resources for this - or explain how to do it ?

Thanks.

Since you have SecureClient, you're OK to use Office Mode. Set up Office
Mode an use RDP probing to find the remote gateway as well as an NGX
version
of SecureClient and all should be well.

Obviously you're better off re-IP'ing the LAN because you'll have the same
issue if you try to set up a site-to-site with someone who also took the
defaults for the LAN addressing scheme.
