for how long can I expect the update servers to be slow?

I'm forced to use the bad router from the ISP because there is no
alternative due to the technology they're using, and despite I'm getting
ip6 addresses, that stupid router doesn't support anything, and thus it
can't do prefix delegation.  So I can't use ipv6.

The bridge the FreeBSD VM is connected to has, IIRC, only a link-local
ipv6 address (starts with fe80) that was assinged automatically.  If
that would cause problems, I'd expect other downloads to be affected as
well, and they aren't.
