Windows Server 2011 not connecting

I'm not able to connect to my v6 tunnel. Traceroutes to the PoP's IPv6 always fail with "Request timed out." Here is the batch script that I am using to create my tunnel connection at startup:

@echo off REM echo Adding interface... netsh interface ipv6 add v6v4tunnel SixXSTunnel 192.168.1.2 66.117.47.228 REM echo Adding address... netsh interface ipv6 add address SixXSTunnel 2001:4830:1600:349::2 REM echo Adding default route... netsh interface ipv6 add route ::/0 SixXSTunnel 2001:4830:1600:349::1 publish=yes REM echo Setting proper MTU... netsh interface ipv6 set subinterface "SixXSTunnel" mtu=1480 REM echo Enabling ICMP echo... netsh firewall set icmpsetting type=all mode=enable profile=all

The tunnel that I am using is T57941. I set the MTU to 1480 in the tunnel's information page. IPv4 traceroutes always succeed as seen:

I've been trying for two days now to resolve the problem and have failed. Any help is appreciated. Thanks in advanced. Also, a small side note: Using the same script to configure a HE tunnel (used as a test) works.

netsh interface ipv6 add v6v4tunnel SixXSTunnel 192.168.1.2 66.117.47.228

You are behind a NAT and would have to configure your NAT box properly for that to ever work correctly.

Yes. The server is DMZ'd.

I would then start looking at interface tables, routing entries and the other things requested on the "reporting problems / checklist" as referenced by that big orange box when posting something.

The issue seems to have resolved itself. I'm unsure how or why, but it suddenly started working.
