Hello, cvsup.cz.FreeBSD.org should accept IPv6 cvsup connections too.
As a quick how-to for the others, you can put
--
#!/bin/sh
nohup /usr/local/bin/socat -ly \
tcp6-listen:5999,fork,reuseaddr \
tcp4:localhost:5999 >/dev/null 2>&1 &

into your /etc/rc.local, or patch socat with

and put socat into rc.local in a simpler form:

The problem is that socat does not survive booting sequence, because
it received HUP signal, which terminates it by default.
Regards.
