Just this, and all was working very smoothly with RC 2 across full C4D host on MacOS and Windows and on Windows TR clients.
<VRLClient>
<LicServer>
<Host>192.168.3.230</Host>
<Port>30304</Port>
<Host1></Host1>
<Port1>30304</Port1>
<Host2></Host2>
<Port2>30304</Port2>
<User></User>
<Pass></Pass>
</LicServer>
</VRLClient>
Now the "license server" button in "about" just launches local instance of the server on each machine, despite that xml being present in the same, correct location.
