Problem is that the desired location isn't available when creating a new tunnel, but the location is listed on the front page.

I need help getting my tunnel setup on FreeBSD / Linux
I cant ping any ipv6 website

Is there no support from this company? I still cannot get help on this issue.

Turns out that the cable modem was blocking 6in4 despite all firewalling being turned off.

I got a different model CM (Netgear CG3000CR) and 6in4 started working again.

No.  It means that you host the zone outside of HE and they serve a copy.  You still have to populate the zone yourself at the master.

Hi,

I've been a HE tunnelbroker user for 11 years using a Linux router behind my cable modem.  I have internet through Comcast and up until today had a SMC D3G-CCR set up in what they call "pass through" mode, with a /29 of IPv4 assigned.  The Linux router does 6in4 for me to the TB and provides my IPv6 uplink. 

Yesterday, this device started randomly rebooting, and they replaced it with a Technicolor CGA4131COM.

My static IPv4s and NATs and stuff are working, and connectivity directly to my outside Linux router interface works too.  But 6in4 appears to have stopped working!

From doing tcpdumps, it appears that the CGA4131COM is blocking 6in4 packets, either outbound, or inbound, or both.

Has anyone had this issue?  Is it something I can get Comcast to fix, or am I boned?

The modem does seem to support native IPv6 w/ DHCPv6 with PD of a /56.  But all I've seen about using this so far are nightmare stories about how the CGA4131COM doesn't properly route the IPv6 subnets it assigns via PD through your customer router.

So for now, I'd like to stick w/ the tunnel.  If there's no way to get them to un-block 6in4, is it possible to say tunnel 6in4 inside UDP or something like that to pass through the comcast network?  Does HE.net support anything other than 6in4?

Ah, so if I set up a slave zone, it will tell the master which IPs have a manual PTR record?

Was looking for this and found out that it's now actually possible to set DDNS for a TXT record. Just needed some trial and error to get it working:

Code: [Select]

curl -k https://dyn.dns.he.net/nic/update -d "hostname=_acme-challenge.mydomain.com" -d "password=mypassword" -d "txt=somevalue"

This works. Only one thing needed for this.
There is an optional parameter for `DDNS` feature to each dns record on the UI. You need to active this feature then generate a secret for that. Use this secret as password in the above command.

When you had the zone set up at dns.he.net, did you enter it as a reverse or as a slave?
The slave option is what you want....

But that means I have to give up rDNS totally to your NS? What about some of my static entries? I won't be able to set them up, right?
