That's, of course, pure speculation... you have to test this.
The quickest check would be to contact http://www4.netbsd.org/, which is=20
the set of IPv4 addresses of www.netbsd.org only. (or check with netstat
or tcpdump, what kind of connection is attempted).
If this does not work, either:
As you can get small pages, I suspect something else - like, the ICMP
transmission from www.NetBSD.org (or intermediate hosts) back to you,
or maybe the ICMP transmission from you to www.netbsd.org, or being
broken, so that path MTU discovery does not work.
Workaround is to set the MTU if the Ethernet interface of your *BSD boxes
to 1452 or 1412, or tell your "router" (is it a NAT box in reality?) to
manipulate the TCP MSS values so that no packet will be created with bigger
