Being a little uncomfortable with a device sitting on port 80, exposed to the big-bad world, I tried to change the web port number of the ATA to 8888, and rebooted.

I get the logon page at port 8888, but then it hangs. So I tried regular port 80 and got in, and the setting says it is port 80 again.

Has anyone successfully changed their ATA's web port number?
