Linksys BEFVP41 V2 -> TheGreenBow VPN Client issues

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

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?

Sorry no suggestion. It is likely firmware or hardware related. Linksys have a good replacement policy, but they usually keep you on the line for 2 hours before they agree with you.

I had the identical problem on a Netgear recently. The VPN would show as disabled. Nothing could re-enable it except forcing it to re-save the configuration. Then it would enable and work for 12-72 hours. Netgear accepted it was a defective router and replaced it.
First suggestion would be to upgrade the firmware, but you have already done that. The other option might be to step back a version or two if you have one available. Sometimes they are available on the Linksys FTP site if you dig around
It is also possible the DDNS service is not updating properly. When the user cannot connect try from a command line testing if the name resolves with the correct IP. Flush the cache first:
ipconfig  /flushdns

at first i suspected the DDNS service, but each time it was properly updated.  I could access the remote administration page of the router by accessing the DDNS name:8080

pinging the DDNS name resolves in the current IP address of the router.

the thing is, it still shows the VPN tunnel as enabled.... just have to "re save" the config and it works again.

I suppose Linksys support is the next best route.
