I am having difficulty getting my tunnel to work with the newszilla6.xs4all.nl usenet server. If I dial a PPPOE connection from my PC and configure the tunnel then everything works 100%
The problem is if I try connect through my gateway(RouterOS), I establish the tunnel on my local machine and I can ping IPv6 servers and can browse IPv6 sites but I can't get my downloads to start. SABnzbd connects to newszilla6.xs4all.nl but doesn't download anything and eventually times out but I can ping6 and traceroute6 the address. I think it's a problem with port 119 and RouterOS but I don't know how to fix it.
In both cases I used the same commands to setup the tunnel
ifconfig sit0 up
ifconfig sit0 inet6 tunnel ::216.66.80.26
ifconfig sit1 up
ifconfig sit1 inet6 add 2001:470:xxxx:xxx::x/64
route -A inet6 add ::/0 dev sit1
If you want, try connecting to my news server (news.snarked.org). You should get a 502 reply, but if you do, then the application connected and port 119 is not being blocked on your end.
Check for a private message. Your port 119 is NOT being blocked. I sent you the log entries that I have when your system tried to connect - for yor examination.
Since you didn't want your IPv6 address posted, that's why I sent it as a private message.
Perhaps port 119 at your preferred news server isn't open via IPv6?
Could be an MTU/PMTU problem. Make sure you're not blocking ICMP. And/or set an MTU on the tunnel interface of 1280. "Connects but won't download" is a classic MTU issue.

Set MTU to 1280 and it's working, thanks.
