Some websites aren't accessible

[djsilas]

Hi All,

I have a problem with HE's tunnel. Most of the IPv6 ready site works perfectly, but there is some exception. E.g. ipv6.freemail.hu, ipv6.iwiw.hu, etc, etc - With HE's tunnel i can't reach this sites. I tried with another tunnel (Sixxs), and it goes perfectly. Somebody has experienced similar problem?
Thanks!

What does a traceroute show?

I get Destination host unreachable on both of those sites.

However both of these

2001:4c48:200:1300::1:0
2001:4c48:200:500::1:1

Are on the .hu network

[cholzhauer]

Those two sites resolve to the same IP address

I don't see where you seeing they resolve to the same address?

right from your traceroute you see different addresses

ipv6.freemail.hu (2001:4c48:2:f::100)
ipv6.iwiw.hu (2001:4c48:2:a::1)

Those are clearly different addresses ;)

But yeah they die at the same place on on HU network from the whois, I would have to assume its an issue on their network??

What does the trace look like when you say it works using Sixxs?  From what I see 2001:4c48:200:500::1:1 is saying he can not get there.

From 2001:4c48:200:500::1:1 icmp_seq=1 Destination unreachable: Address unreachable

[cholzhauer]

Whoops, you're right

They are different sites...I blame it on Friday morning

Thanks for catching that
