I saw no correlation between the two times it happened. If it breaks again, I'll see if I can create a conditions list, however. My office firewall is set to always run the testing tree, so as soon as 96 goes into beta, it will automatically upgrade (I keep a very, very old router around in case I completely mess it up with the upgrade! ). I really hate giving a report that says "this broke." I know you need more information than that. Rod On 12/01/2015 04:39 PM, Michael Tremer wrote: > Hi, > > yes, dnsmasq has some stability issues.
