I have 5 (five) servers (portable versions, ver. 4.6 (build 4602), installed in unattended mode) in a LAN, using callback function to a viewer in another LAN, without LMNoIP ID. How can I identify / personalize in viewer (in advance, before accepting connection) which server is requesting connection to viewer, if all of these 5 (five) servers advertise itself as external public IP address of that originating LAN where is running servers ???...
Thank you in advance for your support.
