Yet another NAT problem
![[ca]](/s/countries/ca.gif) Shadow Hawkins on Saturday, 24 January 2004 21:34:23
I have a linksys BEFSR41 cable/dsl "router" and am unable to send and receive any v6 packets, the host in question is running WinXP (though i have a FreeBSD machine i could use if in doubt). The host is the dmz host.
Any attempts to ping6 anything fail including the ipv6 end of my tunnel.
windump gives me this

from 2001:770:100:17::2 with 32 bytes of data:

Ping statistics for 2001:770:100:17::1:

Any help would be appreciated, just tell me what info you require and i'll be glad to provide it.
Also some other info
POP: HEAnet (iedub01)
Tunnel Type: heartbeat
IPv6 POP: 2001:770:100:17::1
IPv6 Local: 2001:770:100:17::2
IPv6 Prefixlength: 64
IPv4 POP: 193.1.31.74
IPv4 Local: heartbeat
and behind NAT is check in the heartbeat app

Can you connect your IPv6 host directly to the Internet to check if it works without the routers. There are some (or even many) routers around which don't pass IPv6 in IPv4 packets (protocol 41) even if the host is the DMZ host.
Example:
- D-Link DI-614+ - does not work - blocks proto 41 traffic with protocol unreachable
- Linksys WRT54G - works like a charm
