Is there a way to connect to the UC520 IMAP features remotely without using a VPN connection?
you could try forwarding TCP port 143 to the CUE address and configuring IMAP to the outside address of your internet router.
you may need to configure access lists on the UC500 to allow outside connections to 10.1.10.1 or whatever your CUE IP address is.
