VCS Starter Pack in a datacenter (Behinde fixed NAT)

Hi guys,

We have a Telepresence VCS starter pack express server and it was working great in our office on E2 dataline but now after moving it to a datacenter there is a problem with registering a Movi client to the VCS over the Internet.

The server setup now is this:  VCS Starter pack - Firewall/Touter - Internet - Movi

The VCS is connected to LAN (internal datacenter network with one interface and is static NATed to the Internet with a router)

all ports are open in the firewall (inbound and outbound)

And here is the settings in the VCS:

Default Zone - Authentication Policy - Check Credential

Default Subzone - Authentication Policy - Threat as authenticated

Also here is the log of the Movi Registering attempt from the public network (Internet):

Can any one help me in understanding why this happens?

Re: VCS Starter Pack in a datacenter (Behinde fixed NAT)

Hi Moemen,

there are multiple threads on this forum which explains the requirements for deploying a VCS in a private DMZ, which you can find by searching for 'VCS Static NAT'.

In short, when deploying the VCS-E in a statically NAT'ed environment, it is required to have the 'Dual network interfaces' option key on the VCS-E, as this key unlocks the static NAT functionality of the VCS-E.

You can also find more information on this in the VCS Administrator's guide for X7.0.

Regards

Andreas
