I have a tunnel with a routed subnet via Goscomb Technologies. When I run a speed test over ipv6 (using ipv6-speedtest.net) I get a download speed of around 2Mb/s and an upload speed of around 8Mb/s. (My internet connection is 40Mb/s down and 10Mb/s up, which I can achieve over ipv4). Are there any limits set up? Before I changed ISP, I was on a 13Mb/s download speed, and still could only get 2Mb/s download through the tunnel, yet when I originally set it up I was able to get nearly the full 13Mb/s my link could provide. I'm using Astaro Security Gateway v8 for my internet firewall and AICCU server.
