DA client not sending packets - no IPSec?

-

this da server / client environment built in hyper-v mix of virtual , real networks.

remote da client uses teredo , iphttps.
can ping directaccess (dns servers) listed in nrpt,
can ping internal statically configured native ipv6 addresses of internal resources, (2001:480:664a:e::/64)
can ping nat64&dns64 addresses assigned da server internal ipv4 resources. (2001:480:664a:e:b733::/96)

real dmz network, when attempts ping fqdn of server ipv address proven pingable, there no packet sent out nic (wireshark, promiscuous scanning).  message 'ping request not find host bobbysox.tidir.bctest.. please check name , try again.' again, da & internal dns servers still pingable remote client.

if remote da client part of virtual dmz network, boots , communicates da server slew of isakmp messages before establishing ipsec , using esp.

same addressing scheme, , connecting da client , external interface of da server real dmz network, ipsec never established, though isakmp still used.


recommendations in resolving/troubleshooting issue?
thank you.

i have pc has power settings pushed out default domain policy in ad environment. of course on local machine "some settings managed system adminstrator". the machine temporarily no longer in contact domain controller (it's been physically moved , not on same network now) can't updated gpo settings. i believe if edit local group policy won't make difference because of group policy processing , precedence. since it's temporary away ad network, still want use settings of ad user. is there somewhere in registry stored can edit power plan manually until can sync domain? (i need prevent sleeping while plugged in - it's set 1 hour) thanks! allen crist i found site: http://gpsearch.azurewebsites.net/#7916 i able add policy to hkey_local_machine\software\policies\microsoft\power using specs found on site. looks solved issue. i'll report if didn't. thanks! allen crist ...
