That's similar for SNOM telephones. If you want to configure IPv6, the
first step is to disable DHCP/IPv4.

At least in the current firmware versions, they claim they don't block
IPv6 on the "through" port any longer like the version I tested a year
ago. (Well, at least they claim that; I didn't test yet.)

(Actually: they did not properly bridge, and the multicasts needed for
NDP and router advertizements didn't go through.)
