I wouldn't trust
any ISP. I currently have my own router behind my ISP's modem/router. I also have my own firewall rules (inbound & outbound), have changed all passwords from their defaults, and do not use the common (and obvious) LAN subnet of 192.168.0.x. I also use a 63 char totally random WPA-PSK key for my wireless network. In short I'm
very careful.
Port 443 is for HTTPS (secure web server) so my guess is that AT&T's modem/router has a web server interface enabled by default. I'd access the device, from the LAN side, and see if you can turn it off. Even then I'd assume that AT&T has some backdoor into your router. If that bothers you put a 3rd party router between AT&T and your computer(s).
Not trying to cause an uproar here, but there are times when you can trust an ISP with your security. Look at Managed Internet Service through AT&T for instance. We have a ethernet drop and AT&T has their own managed router and service with us. They maintain the router. They ensure that the connection is always up. If the connection goes down, I am notified and they dispatch someone to come out and fix the problem.
I know, its a far cry from home service, but I still thought I should bring that up. Having a managed service where someone is watching the connection and the router is not a bad thing.
