concentrator cannot ping to router

[konn]

Hi,

I have a Cisco 1700 VPN router connection to a concentrator VPN 3005 located in overseas via a 256k lease line.

The concentrator can ping to the Cisco 1700 VPN router ethernet port (private IP) during office hours 0900 - 1800 hrs but cannot ping after 1800 hrs, but it can ping to the router serial port (public IP).

Pls advice how can I resolve this issue.

Thanks

There's obviously a time bound filter applied here, check for any time based filter in the concentrator.
