Dear
I have installed 24 cameras Cisco and in a 1RU server VSMS 6.2.1/VSOM 4.2.1 .
I can see all the cameras via vsom but only in the LAN of the building .
I have configured NAT for the server VSMS / VSOM .
Now I can access from outside of the building at the interface of VSOM client but I can’t view the cameras. and I have the error name_of_cameras Unreachable .
I need some help ,it’s may first installation .
Thanks

Hello,
As far as I understand you also have NAT between your VSMS and cameras. In case of Cisco SD cameras; for MJPEG feed, we have HTTPS-443 and RTSP-554 on control channel and TCP/RTP-Interleaved binary data 554 on data channel. For instance for H264/MPEG4 we have UDP/RTP with the port specified during RTSP setup messages. So your NAT/FW should be aware of these TCP/UDP ports and application level communication.

Hi Scott,
Yes, this is also another important point for the VSOM-Client part of the picture. This can be achieved by putting the external NAT pool and the internal address of the VSMS in different DNS zones (if the same DNS server is used both internally and externally) or you can use local hosts file on VSOM(using internal IP) and client WS(using external NAT IP), and configuring the address of VSMS in VSOM as the hostname. Also you should make sure that the apache config(/usr/BWhttpd/conf/httpd.conf) for VSM is configured with this hostname for the ServerName directive.

I turn off the firewall of the server and I opened the ports TCP / UDP 443/554/1066/8086/5002 and several other ports but I again blocked.
I have no problem to viewing in the LAN, all works well.
I can outside access to the VSOM interface , I can add or remove a camera so I can schedule or delete an archive but I can not see live cams or the archive.
and I have a Server Error message .
Thanks .

Dear Tarek
Please check my second post. VSOM is advertising the private IP of VSMS instead of the NAT address, that's why you are getting endpoint errors.

Dear
I try to nat vsom but still the same problem, I see a try to follow your solution with the presence of an experienced Linux. but in the end I use the EasyVPN solution for remote access.
Thanks
