We have a customer who recently had their modem replaced by Frontier.
The new modem is a NetGear 7550. Previously they were able to connect to their private network via Cisco VPN client; now they cannot.
The only change was the modem, internet connectivity was restored. Reviewing the modem settings, everything appears to be set to allow IPSEC (port 500 is enabled via a port forwarding config), and the VPN settings in Advanced settings are all checked. The dsl connection is PPPoE.
I was not onsite when the modem was changed over (we provide remote tech support), so I am not sure whether the original modem was in a bridged mode or not.
The modem connects to a Cisco ASA 5505. The Cisco ASA gets its outside IP from the Modem.
The public IP did change with the new modem, and we made the necessary configuration change to the .pcf file. The users get a 412 error when attempting to connect.
Frontier has not been much help, especially with the ASA in the mix, and I am frustrated.
Any suggestions are welcome and appreciated.
