A few days ago the BT supplied router at one of our residential homes failed completely and has been replaced by a 2Wire 1800-HG, this in turn is plugged into the GB200 firewall which is then plugged into the LAN switch. The home has internet access and can access email using OWA however the secure VPN's on the firewall that we use to connect to our main servers will not accept any traffic. This means that while the home can get email via OWA they cannot access the remote server based pay system, Exchange through the Outlook client, or any of he shared server resources. None of the settings have been changed on the firewall box which worked quite happily with the original router. Any suggestions would be much appreciated.
