Cellular backup options

What is the physical connection layout for the Cradle point? I understand that the static IP block that I have from Comcast would NOT work during a failover scenario. I can deal with that. However, under normal operation (not in LTE failover), is this configured in such a way that creates double NATing? We have VoIP phones connecting to a cloud PBX, and I would not want to deal with double NAT.

A previous employer of mine had a very large client that used Cradle Point as a backup for each location. The Cradle Point had static IPs as well, so we could set the VPNs to use either the main or Cradle Point IP.

Did they use cradlepoint direct with their own LTE connection? Or did they use the Comcast connection pro solution?

e. They use CradlePoint hardware.
That is what we use a lot for this type of options.Do these devices get the same IP from the cellular carrier all the time? S2S VPNs or other things tied to IPs will be challenged if not.

However I think Comcast uses Verizon under the hood anyway for their cell network. Can anyone confirm that?
Comcast has agreements with all of the cellular networks. Who the underlying carrier is depends on your geo location. This is why they may send you a new sim card if you move to a new area that is serviced by another carrier.
Its' AT&T in most locations we have with them.

I've not tested with static, but the assumption would be that the static would still work.

We are a VoIP vendor and we often use this with clients for VoIP protection. We've never seen any double NATting issues.

I believe that they do.

They were all Verizon.

I just heard from my rep. Static IPs will not work during LTE backup. Once normal service is restored, the IPs are available again, but not during the LTE backup.

Oh, too bad. Not a huge deal in most cases, but not ideal.

I'm really not surprised by this - Making your IPs work across different networks is a pretty huge deal.
Personally - I just want the same IP (the one assigned by cellular) when I'm on cellular everytime - that way a backup VPN route can be setup to that IP, or whitelisted in firewalls for things like PBX's, etc.

That's where more robust VPN design comes into play. Like having a central controller like ZeroTier, or a hub and spoke where you reach out to a central point. End points connecting directly to each other with no coordination is a fragile design.
-
@scottalanmiller Yeah, Our team, when working from home, likes to RDP into their PCs at the office. They use either traditional VPN, or Zerotier. Some of them claim to have issues with Zerotier, claiming it is "slow" for them. I never use traditional VPN anymore and I only use Zerotier if I have to RDP to anything at the office. I never experience slowness of any kind with Zerotier.

Zerotier is was such a game changer for us. Remember the old MPLS / pay a fortune days? DO NOT miss those. -

-
For those wondering, MPLS was proposed in 1997 and defined in 2001. But IPSec VPN was 1995 and other VPNs were older.

Yeah I only dealt with MPLS in a larger global company I worked for previously. They spend SOOO much money on AT&T managed WAN connections. Like insane amounts of money.
