Settings change needed to use AT&T Cell Booster
I'm having issues connecting an AT&T cell booster to my network. AT&T said the following have to be done. I spoke with a customer service representative last week who said I would get a text update, but all I got was a text with a message linking me to a channel lineup. :-/ How can I get ahold of someone in actual tech support for help?
1. DHCP is ON.
Note: For installations where static assignment of an IP address is desired the use of MAC Binding and static DHCP Reservation is suggested. Static IP is not supported.
2. MTU size is set to 1500 or higher.
3. MAC address filtering is either turned off or allows the MAC address of the Cell Booster.
4. IPSec Pass-Through is Enabled.
5. Block Fragmented Packets is Disabled.
UDP Ports
The UDP ports 500 and 4500 are used to establish the IPSec tunnel. The NTP port is required to be open as the NTP sync messages are sent on the public internet for frequency synchronization. All traffic except NTP will go through the IPSEC tunnel and hence only these ports should be unblocked for the AT&T Cell Booster to provide service.
Note: If you have a firewall enabled, the below UDP Ports need to be open to prevent the firewall from blocking communication with the network. Please contact your Internet Service Provider for assistance.
• UDP/ 500 IPSec Port
• UDP / 4500 IPSec Port
• UDP/ 123 NTP Port (Timing Synch)

Hi @newsie78!
So the good news is, that residential IPs are DHCP and there's not a static option, so you're good on #1! Our MTU size is 1500, so you should also be fine on that one.
For the MAC filtering, you should be able to use these instructions to Reject or add the Cell Booster to the filter:
The IPsec passthrough is one that is not something I've run into often, but appears to be related (or similar) to VPN passthrough. The blocking for Fragmented Packets is also not one that I would want to steer you wrong on, but it seems to be directly related to the MTU size referenced earlier.
Perhaps one of our contributors or wonderful Experts can jump in here with more information on that :)
In the meantime, I hope the information provided so far has been helpful!

Ah, no worries! Usually the login address is somewhere in the 192 range, so you would type 192.168.0.1 or 192.168.1.1 )or something else similar) into a browser search bar. If in doubt, you can try just looking up the brand of your modem/router and "login" and it will usually have the correct IP to use, as well as instructions once you're in there :)
