LB2120 DDNS client
I am implementing the LB2120 in the ROUTER mode and am connecting the Verizon modem directly to the input and run everything on the network created by the LB2120. I have a wireless repeater for all t...
Are you still having issues with the LB2120 and DDNS? Have you found a work around?
Others in the community have indicated problems with the LB2120 not being friendly to DDNS.
Sorry for the dely . . . Life got in the way.
Still haven't figured it out.
I'm on Verizon with a Actiontec MI424WR Rev. 1 Modem
There is one WAN port
But my limited knowledge is keeping from figuring this all out.
Many of my devices are crashing through the LB2120 and into the Verizon Modem.
Others devices are not.
I don't really understand why some work and others don't and what to do about it.
It has both a WAN CoAx and WAN Ethernet connection.
Is that "two WAN ports"?
Do I connect the LB2120 to the Ethernet WAN port and my Intranet devices to the LAN Ethernet ports?
Or to the LB2120 ports?
If so, how do I reach devices on my Intranet and how do things inside the Intrnet connect to devices on the WAN Internet?
I'm sure someone is shaking their head at my stupidity. Just trying to understand.

One of the things I have discovered using ping traceroute regarding the LB2120 is that the AT&T network does not use conventional back-bone system that you may observe with a tranditional HSI provider (i.e. Comcast, Charter, etc). The LB2120 will be assigned an IPv4 address, however, it appears to route through AT&T's own private network before getting to the internet backbone. So even if DDNS is implemented on the LB2120, the assigned IPv4 address will not be vissible on the internet backbone.
Even if we went with IPv6 addressing, it is not clear if the AT&T routers/gateways would block external access to the LB2120.
In short: I think implementing DDNS on the LB2120 may be more involved that just implementing some software on the LB2120. It may require coordination with the cell-phone providers.
NOTE: This is MY observation working in the South Bay Area of California.
My applogogies regarding the last post; I thought we were still talking about DDNS.
My router can be configured with 2 WAN ports (you will need to find ADVANCED settins). I needed to estalbish the "fail over" operation (e.g. this is how the router determines if the primary internet has gone down). My cable modem is connected to the WAN and is the primary means by which the router/gateway connects to the internet. I connect the other WAN port on my router/gateway to the LAN port of the LB2120 (see the description in the LB2120 manual). When I disconnect my cable modem from my router/gateway to test the operation, the router/gateway will "fail over" to the cellular network. This takes a couple of minutes AND the performance is greatly reduced, as expected. When I reconnect the cable modem, my router/gateway does switch back from cellular data to HSI data.
My observations: all VPN connections are dropped and even some browser sites need to be refreshed. The "fail over" is NOT seemless.
