TMS - Endpoint IP updated to blank - Behind Firewall
Also keep in mind we had some issues with the TC4.0, TC4.0.1 TMS 13.0 barrier where we saw some issues due to a change in how the endpoints require authentication for the status.xml which made TMS think the system was behind firewall. It should not be an issue on the newer software TC5.x and TMS 13.1 -->
10.36.56.22 is the local IP of the endpoint, and 18.104.22.168 is the public IP address. Their different, and when TMS see's this and it can't get to the local IP endpoint IP, it blanks out the address and sets it to behind firewall.
Re: TMS - Endpoint IP updated to blank - Behind Firewall
Just letting you know we've had the exact same issue. All endpoints internal with no firewalls or ACLs between, TMS 13.2 VCS 7.2. Endpoints are all TC5.1.4 or later, E20s TE4.1.1 or later (it's happened to both TC and TE endpoints).
It seems to happen randomly and I haven't been able to replicate it manually. It's only happened about 6 or 7 times out of 100+ endpoints so I haven't bothered looking into it that much.
EDIT: After reading through the TMS redundancy deployment guide about how if the reported IP address is different to the source address of the IP header then the system connectivity is changed to 'Behind Firewall', could it perhaps have something to do with DHCP and voice/data Vlan assignment?
As an example, a unit that has booted into the Data Vlan, got a template that told it to change its Vlan assignment to 'Auto' and subsequently got a new address in the Voice Vlan? Or maybe just a new DHCP address in the same Vlan?
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
