Netgear Nighthawk M1 IMAP/SMTP Restrictions??

We are out in the country and have rural internet via Fixed Wireless ISP. I got the Netgear Nighthawk M1 ("hotspot") as a backup because the ISP connectivity is unreliable. It is configured as IP passthrough and connected to the FailOver WAN port on my router. This works great, almost, as we never get interrupted. However, when it switches to the hotspot none of our email works. Outlook, MacOS Mail, Windows Mail -- none of the clients will send or receive IMAP/SMTP email. Exchange server connections work fine. We can go to the gmail.com website and use the web interface no problem. But email clients can't connect to any IMAP/SMTP mail servers. (Gmail, iCloud, etc.)

 

Is this restricted somehow on AT&T's end? And if so, why? We can use our AT&T iPhones as a hotspot and that works. It is just the Netgear hotspot that causes this issue.

 

Thank you.

Also discovered that our Ring doorbell appears to be offline when using the Nighthawk for Internet access.

Hello @txElvis,

 

We'd be more than happy to take a closer look into why you're unable to connect to mail servers with your mobile hotspot device. We recommend that you remove the hotspot device from your router setup, try to connect to the hotspot device again by itself, then test your email. Let us know if this helps.

Can confirm I'm seeing the same behavior when using an MR1100 in IP Passthrough mode. Mail clients are broken and Ring doorbell goes offline. Switching it back to regular router mode resolves it, but isn't ideal.

 

OP - are you by chance running a Ubiquiti router?

@UsefulDrivel Yes sir. Using all Ubiquiti equipment. USG and Unifi AC-Pro AP connected to a 8 port PoE switch. (Sorry for the late reply.)

 

@attcares I tried that and if it is in IP passthrough, my MacBook Air doesn't see the internet at all. This could be a problem on my end.

So I turned off IP Passthrough, turned off the WiFi Nighthawk's WiFi, and removed the Ubiquiti USG from the equation and everything is working normally. So using the Nighthawk as the router instead of the USG, but leaving all the other unifi equipment in-place, seems to be an acceptable solution for me. The fixed wireless provider was useless, so we are using the AT&T hotspot as primary and saving $$ to boot.

I have the EXACT same setup with the EXACT same results, except I can't use the nighthawk for the router because I've got so many devices, and it'll only hand 20 connected devices, so it works for a couple minutes then when it runs out of IP's to assign, it throws up on itself, and the only way to do anything with it after that is to do a factory reset.  Losing my mind on this.  I'm probably 30+ hours over the last couple days getting it to work.  Finally thought I had it, then found out I couldn't get email or access my Ring cameras.
