[admin edit] www.leasweb.com is unreachable, rest works fine. == Routing between the different subnets of nlhaa01 is very bad. I have two tunnels within 2001:1af8:fe00::, and one subnet 2001:1af8:fe26:: All connections between the two tunnels are perfect, no problems there. Connections from the subnet to one of the tunnels don't work. After investigating some more, I also found that the www.leaseweb.com website is unreachable from all my tunnel/subnet addresses. That website is on 2001:1af8::214:22ff:fe1e:d380, so this is yet another subnet (2001:1af8::). All traffic to outside Leaseweb's network is working like a charm. For instance www.sixxs.net and ipv6.google.com don't have any problems. This all lead me to believe that routing between different subnets of Leaseweb gives problems, but all other traffic is unaffected. Thank you in advance for looking at this problem.
