Ok, i have a client that is using the Linksys BEFVP41 V2 router. It has the most current firmware. The router is used to update the current IP address through DynDNS.org.
Everything is setup so that a remote user can log in to the VPN using TheGreenBow VPN client. All is well, but after a few days, the connection is lost and the remote user cannot log in.
What i have to do to fix it is to log in to the router, "change" setting and click "save settings." I don't actually change anything, just temporarily change it to something else, then change it back.
After this, the remote user can log in doing nothing else on his side (no reboot or anything is required). This will work again for several days until i have to do it again.
Any ideas on what is causing the problem and what can be done to fix it?
