What is "External IP:Port"? Why are my mesh APs isolated?
I have 3 ZF7962s, all on the same LAN/Subnet, running IPv4.
All 3 ZF7962s are controlled by a ZoneDirector 1106 running 126.96.36.199 Build 17.
I run them in mesh configuration. The ZD connects to the network switch. ZF1 connects to the ZD. ZF2 and ZF3 are located at other locations in my building.
I use the ZD and ZFs in my office for testing, learning, demonstration, and for Wi-Fi site surveys at prospective clients’ locations.
Until recently, all 3 APs had a blank External IP:Port.
Within the last two weeks, all 3 of them began to display an External IP:Port of :12223.
Today, all 3 APs are displaying an External IP:Port of :12223.
The connection mode is L3 (IPv4) on all 3 APs. I am not certain why this is.
Furthermore, the two mesh APs became isolated. Now, they are disconnected.
This is a 100% layer 2 environment, that has been online for two years.
This problem first appeared two weeks ago.
At that time, I switched from AT&T U-Verse DSL to Comcast cable for our Internet connection.
The DSL modem IP address was 192.168.1.254.
The cable modem IP address is 10.1.10.1.
I has set static IP addresses in the ZD of 192.168.1.111 (ZD) and 192.168.1.112, .113, .114 (3 ZFs).
After I switched to Comcast cable, I could not access the ZD.
The WLANs that I had created in the ZD, still appeared on our iPhones and laptops, and, these devices could still connect to them.
I connected the ZD to the AT&T DSL router. I accessed the ZD, and, I disabled the static IP addresses
I connected the ZD to the Comcast gateway. I accessed the ZD, and, I saw that the Comcast gateway had assigned 10.1.10.17 to the ZD, and 10.1.10.18, .19, .20 to the three ZFs. This is when the problems started to occur.
What does the External IP:Port tell me?
How can I resolve these issues (External IP:Port, mesh isolation/disconnect), and, return my system to proper working order?
Once I resolve these problems, should I, or, should I not configure the four devices with static IP addresses?
