We have changed the firewall between VCS-C & VCS-E and are now using NAT.
VCS-C has internal address: 10.1.99.33
VCS-E has DMZ address: 10.0.1.67 and NAT (public) address is: 194.187.114.13
My external endpoint IP is: 192.68.151.82
I've started TCPDUMP on both VCS-C & VCS-E.
The call from external to an internal endpoint is correctly setup. But I've no audio & video in both directions.
On the VCS-C I see RTP stream from internal endpoint to VCS-C
and a RTP from VCS-C to NAT (public) address of VCS-E ! Why is this not the DMZ address of the VCS-E.
On the VCS-E I see RTP stream from my public endpoint to DMZ IP of VCS-E. But I do not see any RTP stream (or other streams) between VCS-E and VCS-C...
I've double checked all settings.
Traversal zone is defined with DMZ IP of VCS-E and is active in Assent for both SIP & H.323.
This VCS-C VCS-E was working fine before. The VCS-E was then using only a public IP without NAT.
The Dual NEtwork license is used and LAN1 interface is set to External with NAT active and IP correctly set.
Both VCS-C & VCS-E are running X6.1.
The FW guys do not see any lost packets.
Any ideas?
