Hi, there
Sorry for disturbing you.
I use dnsmasq as default dns server on my openwrt(14.04) router, and my router ip is 192.168.88.254.When I connect PC to the router, its network interface obtain the ip 192.168.88.193, and dns server is 192.168.88.254.
Then I visit some websites to generate some dns requests. Sometimes PC can't send dns request successfully. ICMP tells me port 53 unreachable.
If I change PC's network interface dns server to another, such as 114.114.114.114, dns request send successfully. If I change back to 192.168.88.254, problem comes again.
Does anyone know why this happened?
Because of the 40KB size limit, I can't past wireshark capture packets or snapshot here, if you wanne wireshark packets please contact me or visit http://pan.baidu.com/s/1ge8OaVT
Thanks in advance.
