Almost got it working, but not quite... Help?

[johnstray2001]

I have setup a Ubuntu Server 16.04 device that will act as a dedicated IPv6 gateway for my network, however I'm having a bit of an issue getting the HE tunnel working properly.

While testing IPv6 internet connectivity, I get the following results:

Working:
- Name Resolution is working - NSLOOKUP and DIG can both return AAAA records for domain names - Using Google Public DNS (IPv6 address [2001:4860:4860::8888])
- Ping is working - Ping6 to multiple different domains returns a reply with an average time of 400ms <-- a bit slow?

Not working:
- WGET is not working - Using wget to test ability to download plus connection speed test fails.

The same thing happens when manually specifying the IPv6 address instead of the domain name to wget.

I've done a fair bit of searching around and nothing I've tried, such as reducing the MTU to 1472, seems to help.

Notes:
- The server is in my router's DMZ
- Router is a Sagemcom F@st 3864 VDSL2+ (No idea if it passes Protocol 41 - Considering what I can do, I'd say it does)

If there is any other information you require to help me get this going, the please let me know and I'll post back.

Thanks in advance for any help you can provide.

Why does it have to be wget? Why not something like http://ipv6-test.com/

I'm using Ubuntu Server, so no graphical interface, only command line.

I'm using Ubuntu Server, so no graphical interface, only command line.

apt install lynx
or
apt install links
No more excuses because "only command line" ;D Welcome to 1995 :)

[johnstray2001]

So, installed lynx...

Same problem. It just sits there trying to connect. Nothing happens.

Does anyone have any suggestions?
