I setup a HE IPv6 Tunnel which is "working" so far. I can ping IPv6 Hosts in the internet. The tunnel has very little latency (< 25 ms) and pings are working reliable. HE Server IP is: 126.96.36.199
But I'm not able to get more than 1Kb/s trough the tunnel. The bandwidth of the tunnel is just very very terrible. I tried many different MTU's from 1452 to 1280 and they all didn't seem to make any difference.
I did make a HTTP request via CURL on a Linux box: https://youtu.be/0-BJNQR8UT8
The same happens if I run CURL directly from pfSense (which is connected via PPPoE).
Here are two screenshots demonstrating the issue:https://imagizer.imageshack.us/a/img922/8234/G4Bmoc.pnghttps://imagizer.imageshack.us/a/img924/3689/canEeA.png
I tried to upload these screenshots here, but it failed with the message "Couldn't access files to upload".
I'm running pfSense 2.3.2-RELEASE-p1 (amd64) got a IPv4 bandwidth of 50 MBits/s
Do you have any idea what I'm doing wrong?
Thank you for your help.
