I am having issues with my IPv6 connectivity via Windows Server 2008.
External traceroute shows each hop along the path, including the servers gateway. It then times out, never reaching the host.
From the host, I am able to ping the same gateway, cannot reach anything past it.
I have tried setting static routes to some external IP's I own, resetting the routes, and every combination that I can think of without luck.
Right now, I cannot help but think the router is not forwarding ipv6 packets...but I have been assured by netops that it is functioning correctly. As I am not completely familiar with ipv6 and Windows, I am hoping there is something trivial that I am missing.
Any help is appreciated. I will update this question with any information requested.
Server->Gateway{2001:db8:1:6::1} - Ping OK
Internet->Gateway{2001:db8:1:6::1} - Ping OK
Server->Gateway{2001:db8:1:6::1}->Internet - Not OK
Internet->Gateway{2001:db8:1:6::1}->Server - Not OK
Server IP Address: 2001:db8:5678:7890:65c2:c257:37c3:40f7
**First 64 of all IP's changed. All ping/traces have been done exclusively with IPv6.

Your routing table looks reasonable (aside from a strange route to a /96 but that probably isn't causing you any issues).
At this point it's time to look at the Brocade router that's serving as your default gateway and make sure that it's behaving properly.
