Description
|
||
-----------
|
||
|
||
With changing IPv6 prefix from ISP this script handles to update...
|
||
|
||
* ipv6 firewall address-list (prefixes (`/64`) and host addresses (`/128`))
|
||
* 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;
|
||
|
||
As this entry is mandatory it is created automatically if it does not exist,
|
||
with the comment also set for list.
|
||
|
||
Address list entries for specific interfaces can be updated as well. The
|
||
interface needs to get its address from pool `isp` and the address list entry
|
||
has to be associated to an interface in comment:
|
||
|
||
/ipv6/firewall/address-list/add address=2003:cf:2f0f:de01::/64 comment="ipv6-pool-isp, interface=br-local" list=local;
|
||
|
||
Updating address list entries with host addresses works as well, the new
|
||
prefix is combinded with given suffix then:
|
||
|
||
/ipv6/firewall/address-list/add address=2003:cf:2f0f:de01:e3e0:f8fa:8cd6:dbe1/128 comment="ipv6-pool-isp, interface=br-local" list=hosts;
|
||
|
||
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;
