One of those machines came up earlier than expected, so I could try it now. I 
get the same "Permission denied" type errors, even earlier than with the host 
on the fxp0 subnet:

# nmap -sS -vvv -O 192.168.3.11

Starting nmap V. 2.53 by fyodor@insecure.org ( www.insecure.org/nmap/ )
Host tom.bland.fido.de (192.168.3.11) appears to be up ... good.
Initiating SYN half-open stealth scan against tom.bland.fido.de (192.168.3.11)
sendto in send_tcp_raw: sendto(3, packet, 40, 0, 192.168.3.11, 16) => 
Permission denied
Sleeping 15 seconds then retrying

However, I know that 192.168.3.11 is running a block-really-everything ipchains 
firewall, so maybe that has also something to do with it. 192.168.1.2, however 
(the one I scanned in the fxp0 subnet) is an OS/2 machine without any sort of 
firewall.

Viele Gr��e,
