Problem with config of WRVS4400n

[vikkam]

I have WRVS4400n at home.

I am connected to network at my work over internet.

I used to have continuous connection from work to home.

Now periodically I have to reboot the home router

so that I can connect from work.

Connection from home to work is always on.

Once rebooted it works fine till the connection goes off.

I think it is 24 or 48 hours when it happens.

Attaching screen shots of config.

Will really appreciate help as the disconnection debars me from

accessing files on home computer.

Do you have trouble with IPSec VPN or QuickVPN? Could you provide a network diagram to help us understand your issue?

[David Carr]

When the tunnel goes down, do you still have access to the internet, the local network?  This will let us know if it is an ISP issue or a router solely issue.

I have access to Internet and every thing else.

Itis just the tunnel that goes down.

Once I reboot the router it comes back.

I believe it is VPN tunnel.

I seen in the attachment that your using dyndns on your router.  And that your getting your wan ip address dynamically.  Is your wan ip address changing when the tunnel disconnects or is it staying the same.  The reason i am asking is if it is changing the tunnel will go down independently and the internet will stay up.  Since there is no static ip address to maintain the connection your at the mercy of the address not changing.

Thanks for prompt reply

The ip address remains the same
