[Dnsmasq-discuss] Problem with OpenWRT + dnsmasq

[Juhani Talvela]

Hi,

Sorry, but there is just this one PC connected to the router LAN port. 

When dnsmasq is running, there is a huge number of connections all aimed at the ISP nameservers with port 53. If the mailing list allows images, you can see the connection and traffic loads attached, here.

When I stop dnsmasq, all connections are dropped and no excess traffic is visible.

Wonder if I should stop using dnsmasq and go for dhcpcd, instead?

Cheers
Juhani

When dnsmasq is running I have a constant load on my router processor of about 20-50%. Additionally, there is a constant download load on my WAN of about 8-12 Mbps ( I have a 20 Mbps Internet connection).

---------------------
It sounds as if there is another computer (possibly unauthorized) on
your network which is generating the traffic.  Since you aren't
putting a static IP or DNS configuration on that other computer,
wherever it may be, it doesn't work when dnsmasq isn't running.  But
the problem is not dnsmasq itself.
