Dynamic DNS update another PepLink Balance (with fixed IP address)

The lack of Dynamic DNS providers with free services, or paid services with a reasonable price and located in Europe are non existent.

Therefore additional dynamic DNS update mechanisms need to be in place. Like the already earlier requested nsupdate method to update a BIND DNS server, EPP to update directly at the tld registry.

Another feature request is to be able to update the WAN IP address at another PepLink Balance device.
