dhcp6c releasing allocation
There is a problem some users are having with dhcp6c sending a release on exit, in 99% of cases this is not an issue as the BNG will look at the DUID on the next request and give the same allocation. However, there is at least one ISP in the UK that is using a 'sticky' dynamic and the release causes the BNG to do exactly that and next time around and new range is given.
I have written a fix for this by adding a a no release option to the dhcp6c client, it works and has resolved the issue, Merlin has a similar fix for Asus routers.
For the life of me I cannot work out how to do a pull request on the FreeBSD ports to get this to be included in the main pfSense/FreeBSD-ports code.
I have also added an option to interfaces.inc and interfaces.php to control the 'no release' and I know how to do pull requests for those, and I will do so once the dhcp6c client has been updated.
Any help much appreciated...
