|

Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
With changing IPv6 prefix from ISP this script handles to update...
|
||
|
|
|
||
|
|
* ipv6 firewall address-list
|
||
|
|
* dns records
|
||
|
|
|
||
|
|
Requirements and installation
|
||
|
|
-----------------------------
|
||
|
|
|
||
|
|
Just install the script:
|
||
|
|
|
||
|
|
$ScriptInstallUpdate ipv6-update;
|
||
|
|
|
||
|
|
Your ISP needs to provide an IPv6 prefix, your device receives it via dhcp:
|
||
|
|
|
||
|
|
/ ipv6 dhcp-client add add-default-route=yes interface=ppp-isp pool-name=isp request=prefix script=ipv6-update;
|
||
|
|
|
||
|
|
Note this already adds this script as `script`. The pool name (here: "`isp`")
|
||
|
|
is important, we need it later.
|
||
|
|
|
||
|
|
Also this expects there is an address assigned from pool to an interface:
|
||
|
|
|
||
|
|
/ ipv6 address add from-pool=isp interface=br-local;
|
||
|
|
|
||
|
|
Sometimes dhcp client is stuck on reconnect and needs to be released.
|
||
|
|
Installing [ppp-on-up](ppp-on-up.md) may solve this.
|
||
|
|
|
||
|
|
Configuration
|
||
|
|
-------------
|
||
|
|
|
||
|
|
An address list entry is updated with current prefix and can be used in
|
||
|
|
firewall rules, comment has to be "`ipv6-pool-`" and actual pool name:
|
||
|
|
|
||
|
|
/ ipv6 firewall address-list add address=2003:cf:2f0f:de00::/56 comment=ipv6-pool-isp list=extern;
|
||
|
|
|
||
|
|
Static DNS records need a special comment to be updated. Again it has to
|
||
|
|
start with "`ipv6-pool-`" and actual pool name, followed by a comma,
|
||
|
|
"`interface=`" and the name of interface this address is connected to:
|
||
|
|
|
||
|
|
/ ip dns static add address=2003:cf:2f0f:de00:1122:3344:5566:7788 comment="ipv6-pool-isp, interface=br-local" name=test.example.com ttl=15m;
