Yes, indeed. And I bet that the router's internal DNS cache server
causes the problems.

Alasdair:
What does the output of "ifconfig -a" on your NetBSD system look like?

A work-arround would to be to run a local caching nameserver:
1.) Add "named=YES" and "named_chrootdir="/var/chroot/named" to
    "/etc/rc.conf".
2.) Start the nameserver with "/etc/rc.d/named start".
3.) Change the nameserver in "/etc/resolv.conf" to 127.0.0.1.
4.) Try whether the various applications work better now (after
    restarting them).
