Nice ;-)

I’ve been doing this for some time already … and have trials with several customers (tens of thousands of customers).

Note that most of the routers that support LEDE (quite a big list), will work by default with a standard stable release.

You mention it, but we use something like for the offload:
ethtool --offload eth0 gro off lro off
ethtool --offload eth1 gro off lro off

Also, for the DNS64, I use exclude. It can be improved also to avoid including (in the exclusion) the prefixes for transition mechanisms, such as 2001::/32, 2002::/16, etc.

dns64 64:ff9b::/96 {
clients { any; };
mapped { any; };
exclude { 0::/3; 4000::/2; 8000::/1; 2001:db8::/32; };
break-dnssec no;
};

I’ve an ID on this:

I’m working in the next few days in a review of this, so any inputs are welcome!

Regards,
Jordi

Asunto: Implementing 464XLAT at a small WISP

    We recently deployed our first half-dozen IPv6-only customers after 6+ 
    months of testing, using 464XLAT.
    
    It took me ages to sort all this out, so I hope someone finds this 
    helpful. Feedback very much welcome.
