VCS Control and VCS Expressway design

[e.lopessilva]

I have an implementation where I have 2 VCS Control and 1 VCS Expressway software version X6. The end costumer has a Internet firewall Fortinet woroking in routed mode with NAT. My question is about the placement of the VCS Expressway in the environment. Is it mandatory put the Expressway in front of the firewall with a Internet valid IP address on it? Is it possible put the Expressway behind of the firewall and configure a NAT for it? Make sense having VCS control and VC expressway in the IP subnet without NAT between them?

Thanks in advance.

You can log in as root via SSH and use ping, traceroute and nslookup from there.

If Google DNS is not working for you, you most likely have a firewall issue.

I switched back to the google DNS and nothing the I did a reset after the reset now it is working.

Thanks for the support...

Do you know if there is a guide to deploy the ISDN blade for the MSE8000?

Alejandro,

I'm pleased to hear it's working now.

As with all Cisco Telepresence products, support documents can be found at www.cisco.com/support.

For Cisco (Codian) ISDN Gateway products,

http://www.cisco.com/en/US/partner/products/ps11448/tsd_products_support_series_home.html would be the right section to look in.

For your info, the new VCS Basic configuration guide for VCS Control and Expressway has now been released for X7.1.

This new document contains a new appendix (Appendix 4) covering Dual NIC and Static NAT deployments in detail.

The new guide can downloaded here.

Comments and feedback for the document in general and the appendix in particular is appreciated, so feel free to PM me with this if possible.

Regards

Andreas

Andreas,

The documents that you refer to are not complete enough.  The NAT discussion is non existant and that is key to any installation.  The NAT section points to the port usage guide which does not discuss NAT at all.  This document should be similar to the integration guides that Cisco publishes for PBX integration with CUCM.  These guides go through all the details of each of the devices involved.  In the case of VCS that would mean covering an example firewall and endpoints.
