* Is the Amahi [http://www.amahi.org/apps/openvpn OpenVPN] application installed in your HDA? (this is not required if you are on Amahi Fedora 14, but required on all later releases)* Make sure your HDA's network IP range is different than that of the remote network. (e.g. if your HDA's IP address is 192.168.1.X, you cannot connect to it on a remote network also using 192.168.1.X) * If you are running your HDA from a Verizon FiOS connection, you may experience strange disconnections. This may be due to the Actiontec router's small NAT table. Please see guides [http://www.verizonfioswiki.com/index.php/Using_Your_Own_Router here] for instructions on how to use your own router. * If you have a Vonage V-Portal (or perhaps other voip adapters as well), plug your router into your modem, then the v-portal into your router. Vonage tells you to put the v-portal between the modem and the router, but I was unable to connect to vpn until I moved the adapter behind the router. * Check out [[VPN_troubleshooting|VPN Troubleshooting]] for more troubleshooting tips.
