Hello,
Sorry for the delayed reply.
The RUTX11.lan is okay, as that is the hostname of your device.
I would suggest factory resetting your device, as there may be some other rule missing that could prevent the traffic from reaching the other end.
Also, are you sure that the Remote source IP needs to be specified in your configuration?
I will also ask you to enable the Compatibility mode in Advanced connection settings, as it sometimes helps when connecting to Cisco devices.
Let me know if these steps help.
Best regards,
