Site to Site VPN Using D-Link DI-804HV and Netgear Prosafe DGFV338 ADSL Routers

We have taken on a new customer who has 4 remote sites which are connected via VPN router to router.

1 site has stopped working. When looking at the VPN logs I get the following messages...

I have tried to create another VPN using the same settings but still get the same error message. As far as we can tell nothing has changed as the other 3 sites are working fine.

I have update the ADSL and Router firmware on the Netgear Prosafe.

Can anyone help me try and find out whats going on?

do you have clients connecting to the netgear?  try disabling the keep alive on the netgear and post back.

Also - look at the logs on the other end, since it may contain more info.

Do you have any saved config ?
Can you compare the settings of the other routers ?

What has changed ?

It may be cheaper to buy another router to test with,

ALso - is there a Dynamic address  involved ( not a static IP ), that may have changed ?

After some hours of going over the settings again and again I found the PassPhrase to be incorrect on the D-Link Router.

Recreated the rule again and now connects OK.
