Communicator Works Internally, Not Externally

Communicator Works Internally, Not Externally

(OP)
Guys,

I have a site that I setup Communicator and it works in the office, but not remotely over VPN. I have enabled Remote SIP Extension and enable Remote Worker. System is IP500v2 R.10.0.4. The customer seems to have done a thorough job of checking firewalls and such, but still not working. I see the message about No public address provisioned, but I don't know that that means.

Any ideas.

Thank you,

RE: Communicator Works Internally, Not Externally

If you're using VPN you don't need to enable remote extension.

"Trying is the first step to failure..." - Homer

RE: Communicator Works Internally, Not Externally

Sound as if some NAT is in place over the VPN connection.

RE: Communicator Works Internally, Not Externally

(OP)
I checked with the customer and it looks like they are using NAT over their VPN. If so, what is the resolution?

Thank you,

RE: Communicator Works Internally, Not Externally

Disable NAT?
