I just turned up my AXE300.  Simple router to set up  I have run into an issue though where I am trying to enable IPv6.  There isn't a 6rd manual setting option so I used the auto setting and it detected a 6to4 setup.  It was able to get a /48 allocated and assigned a /64 on the LAN as it should.  I can ping the gateway IP as well as the tunnel address.  I can't ping past the tunnel address.  To me that seems to indicate that either there isn't a route out or the firewall is blocking access.  Anyones else had this issue?
