Because of some other issues faced in day to day life, I could not work much on BKO :(

7 Aug

Performing the tests of DNS that warthog9 had requested.
Attempts to use external DNS server fails with following error

[15:38:13][9][~]$ dig www.google.com @4.2.2.2

; <<>> DiG 9.5.1-P2 <<>> www.google.com @4.2.2.2
;; global options:  printcmd
;; connection timed out; no servers could be reached
[15:38:29][9][~]$ 

but Internal DNS server works fine as follows

[15:44:57][0][~]$ dig www.google.com

; <<>> DiG 9.5.1-P2 <<>> www.google.com
