I've just done it successfully with one of my domains.  If your domain is example.com and the subdomain is foo.example.com, first create NS records within your example.com zone like so:

Code: [Select]

foo.example.com.      86400 IN NS ns1.he.net.
foo.example.com.      86400 IN NS ns2.he.net.
foo.example.com.      86400 IN NS ns3.he.net.
foo.example.com.      86400 IN NS ns4.he.net.
foo.example.com.      86400 IN NS ns5.he.net.
You will then need to wait 10 mins for HE nameservers to catchup, then 'Add a new domain' from the menu and enter 'foo.example.com'

I don't remember offhand which version fixed it, but I'd grab the latest one and avoid some of the bugs along the way.

What version do you recommend?

I recently set up a raspberry pi mail server and was hoping to get SMTP unblocked, so that I can receive and send mail directly. (I do have Sage).

I submitted my request from the email account associated with my tunnelbroker account to ipv6@he.net on Friday night, but have not received an automated response with a ticket number.

My tunnelbroker username is also 10010 and the request was sent through my Gmail account, if that makes a difference.

Thanks in advance

Old versions of anyconnect don't support the 6in4 stuff

You need to upgrade

There is a router upstream from the firewall, it is a Cisco 2951. The router is using IOS 15.5(3)M7. The tunnel is terminated to the edge routers.

I know this thread is ancient, but I wanted to provide closure to anyone with the same issue.

The stock firmware on the Linksys E4200 is all-around buggy, and I have since upgraded to an EdgeMAX router, and relegated the Linksys E4200 to switch duty. This new router works wonderfully and tunnels persist after I reboot the router (which is rarely necessary).

In short: the issue was with my cheap router.

That's most likely your problem.   Newer versions of both support tunnels where the old ones don't

Hello, I am using Cisco ASA OS 9.1.7 and Cisco AnyConnect 4.5

What version of anyconnect and what version of the Cisco OS?   Older versions do not support 6in4 tunnels
