Hello,
I have configured DNS forwarding on my Cisco 2821 to ISP DNS servers and configured router as a DNS Server for all of desktops/laptops I use. Everything work correct but only for 48 hours (approximately), then I cannot access/ping several websites (note that only couple not all) until DNS cache of the router is cleared. After issuing clear host all * everything is ok for next 48 hours...
Is there any way do fix that?
Thanks.

Is there any way to configure clearing dns cache automatically? Maybe I missed smth in config?
