Hey, so the problem is this:
May 20 07:45:45 quasarapp dnsmasq[5242]: failed to create listening socket for 10.235.69.1: Address already in use
Something’s sitting on the port dnsmasq tries to take. Do you have named running? Or some other dns/dhcp process?
The output of netstat -ap | grep ^tcp | grep LISTEN may be helpful.
