Subnet not working. Tunnel runs fine
 ![[de]](/s/countries/de.gif) Shadow Hawkins on Wednesday, 12 November 2008 07:56:35
Hi,
my assigned subnet 2a01:198:302::/48 seems to be not working correctly. If I dont't configure any IPv6 address except that of my tunnel endpoint, I can ping6 outside and the endpoint on my side is reachable from outside. But when I configure an address from my subnet, I can't reach the machine any longer as well as I can't reach it from outside. The following traceroute's show what's happening:

To me this seems to be a routing issue. Can you please check this?

Just wanted to drop a note that I seem to have the same problem:
My OpenBSD router running the IPv6 tunnel (aiccu) has connectivity:
