Ticket #1423 (closed: fixed)
IPV6 MTU issues (including tunnels)
|Reported by:||narsty||Owned by:||cmaloney|
setup is a SIXXS AYIYA tunnel, and a plain lan of ipv6 clients, default radvd.conf parameters
downloading this following
firefox just gets to 'waiting for heanet.dl.sourceforge.net'
(as does filezillas own update system, it client program the file itself)
after talking in #ipv6 on freenode i'm told :
"there's a problem with the "packet too big" messages not getting back to the server
the tunnel server will be rejecting 1500-byte packets (with "don't fragment" set) destined for you
it will send an icmp packet to the source when it does this, telling it the correct MTU"
