Running ROS 6.35.2
RB 2011UiAS (though have seen issue on other routers)
Customer connects and is able to ping out and open some websites. Other sites (which are almost always predictable across the client base i.e.: crucial.com, eyeonwater.com, msn.com, download apple app store items) DNS times out in getting information.
Take a Netgear router. Pings, routes out, just does not connect to these websites. Same with Dlink and Apple router. Other websites are just fine.
IF I hardcode the DNS to external DNS into the computer, iPad, Android things WORK - I can get to all sites.
IF I put in a Mikrotik (750,951,941,...) router with DHCP network assignment to tell DHCP-clients to use external DNS servers things WORK.
Solution of hardcoding external DNS or Mikrotik replacement with external DNS in Network assignment works everytime.
PROBLEM does not effect every client on network. Only some. Have many clients with third party rulers working just fine.
Comments? Solution with without the intervention? Why does DNS not passthrough third party router to client network devices? Why, when using the client router as the DNS proxy(?), not work??
Problem seemed to be introduced into 6.34 and continues ....
