secure home network

Many people now have home networks and would like to be able to access our home security cameras in a secure manner.  My sytem wants to do that via DynDNS but it seems your 5268AC FXN is at least 8 years old.  /////////////////////////////When will ATT show some concern with my security and address this problem with a new router for Fixed Wireless service?

As users we've always had the option of using our own WiFi systems.  I see no signs the native WiFi design in Att gateways is going to get better.  Good luck.

@Veridical There are going to be a couple issues that you will have with this service:

1) ATT Fixed Wireless / Internet Air uses carrier grade NAT (CGN in other posts) which means that you do not have a public IPv4 address to go to for your network.  DynDNS is simply linking some hostname to your public IP address so that you can find your equipment when you are outside of your house.  Since you don't have a public IP, this is not possible.

2) ATT gateways have never supported updating dynamic DNS directly from the gateway.  Most consumer routers support many different implementations, but ATT routers do not.  You could still do it with another device behind the gateway - if you had a public address.

As for security, it is likely that IF the cameras actually implement SSL, they are using a self-signed certificate which is encrypted, but not recognized by any devices as a trusted certificate. If the cameras do not implement SSL (https), then all your traffic is visible to any router along the way, passwords are sent in clear text, etc.

There are multiple ways to make this secure and make it work, but the one I've landed on is to host a VPN server at home that I can log into.  This gives me access to all my devices (cameras, printers, lights, thermostats, etc.) over an encrypted tunnel.  Since you don't have a public IP4 address, you can only do this with a IP6 tunnel (which you should have public, globally routed addresses available) and your remote device must have an IP6 connection.

Good luck.

@Veridical  Some third party routers have isolated the Guest Network from your Primary network so you could use the Guest Network for your IoT devices by assigning it a different SSID and it's own pw separate from your Primary network.

@fr8sho The Company has always told me i cannot use my own router.  Do you have a link to instructions on how i can use my own router with this Fixed Wireless system?

@Veridical  AT&T's fixed wireless service (AT&T Internet Air) uses a different technology than their land-based internet (cable, DSL, fiber) so you are stuck with the router for their Internet Air. Land-based is different because you can use a router of your choice if you place the gateway in IP Passthrough mode, but that option does not exist for the Internet Air.

Sorry, didn’t catch the FWA part.  Will Att let you upgrade your service to Att Internet Air?  It uses a more standardized version of code and hardware from what I understand more in line with their existing gateway devices.

I am right at the edge of the limits of a cell tower: 5 miles.  Fixed Wireless uses a boosted external antenna powered by my house electric.  I don't know what the "FWA part" means.

@Veridical  FWA = Fixed Wireless Access, which sounds like what you have.

Yes, is there a way i can use my own firewall and my own router?  I had seen some comment that it may be possible to set the 5268AC FXN to pass through.
