Hi,
We are running into a problem with Cisco Mobile Remote Access where the DNS 
entries we created are being replicated on the inside and outside of our 
firewall. The users/devices attempt to connect to the correct services 
(_cisco-uds_tcp & _cuplogin._tcp) from outside of the firewall and because our 
DNS entries are replicated on both the inside and outside these lookups do not 
fail but the registration does eventually fail because these addresses are 
internal IP’s. The users/devices never get prompted to lookup the (_cisco-uds) 
through Expressway and thus are unable to register.
Is there any way to configure an ACL/whitelist/blacklist entries for certain 
zone entries within Cisco Network Registrar which would enable outside 
users/devices to hit the Expressway as opposed to the internal IPs of the Call 
Manager/ CUPs server?
Any ideas?
Thanks,
James
