I have a Lync 2013 edge server straddling my DMZ one nic in the DMZ configured with DMZ gateway and from the Edge server I can browse the internet through this nic. The other nic is in my trusted zone and has no gateway configured and no DNS configured.
If I look at my Route table for the server I show ::/0 going to my DMZ gateway (which is correct) and I show my internal IPv6 subnet with my trusted zone ipv6 gateway.
I can ping my trusted zone gateway, but I can not ping any of my internal computers, and none of them can ping my edge server. There isn't any firewall or router in between my servers in my trusted zone and my edge server as the internal nic is in my trusted zone. The edge server is a workgroup not a domain joined computer.
Once I confirm that the edge server can talk with my front end server then I will install internal and external certificates on the edge server.
Not sure what I am missing that is preventing my Edge server pinging servers on my lan (tried, DHCP server, DNS, and of course the Lync front end server - all by ipv6 addresses). I tried temporarily turning off the firewall on my frontend lync server to see if it was not accepting ipv6 ping from a non-domain computer but that did not work.
I think there is something wrong with routing.
