We have a handful of locations where we still use AT&T ADSL for Internet. We use a Cisco ASA 5505 Firewall at these location to create an IP Sec Tunnel back into our company network. We static ips from AT&T in order to make this work. We have had these connections set up for some time. In the past we had even more.
We used to use the Motorola/Netopia ADSL Router at these locations. AT&T has stopped using these and due to out of date firmware and the fact that AT&T no longer supports the Motorola, we are using a Netgear ADSL Router that AT&T supplies (we do have to buy them) which they do support.
Now that we are using the Netgear Routers we have a connection issue at all of these locations. Sporadically, but at least once or twice a day the location will lose connectivity. A reboot of the Netgear router is necessary in order to get it back up.
AT&T, though, says it is our equipment as they show the circuit never went down.
Any help will be appreciated.
