Charged for public, static IP addresses but ATT can't make it wortk

For the monthly fee you are assigned a block of 8, of which 5 are usable in AT&T's assignment scheme.  The fee for the /29 block used to be $15/month, but announcements were sent out that it was going up to $30/month.

Did AT&T give you the base IP address of your Public Block?  If so, and if you know what you want to do with it in your network, we can tell you how to set it up.  Support will likely not be able to refund any money for the service, but they could likely cancel it for you.

@wissen I have the static IP block for my AT&T fiber setup and it's working great, and I'm using my own Juniper firewall as the router and gateway for my home business setup. Some things to keep in mind:

1) Your router will need to be configured with the public IPs you were given

2) The netblock is a /29, which is eight IPs but with the network, gateway, and broadcast addresses used you get 5 usable.

3) For #2 I think it's a sales bait and switch - the salesperson said "We have a package of eight IPs for $30"

4) You'll want to use 255.255.255.248 as your subnet mask, and the gateway is one higher than your last IP.

5) On the AT&T router you have to set it up to use the passthrough option, and there's a list of connected devices for the manual passthrough.

6) Look for your router's MAC in the list and set it to use that as the passthrough device.

One thing I had to do, which you may not need to do, is on the Juniper I also has to set up proxy-arp to ensure the SRX firewall passed on it's mac to the AT&T router.

Did you not get one public address with your account?  You can set up your ATT supplied modem to do "pass through", and then that ip is passed to the router behind it.  one can get arount much of the limitation of NAT by  using Cloudflare to provide secure access to internal resources.
