I have continued to experiment and I am happy to report that the test  
program httpd_sequential.c builds and executes. But only if I build the  
library with a fixed IP-address for my board. When changing this to DHCP,  
I can no longer reach the http-server running on my board.

Using wireshark, I can see (see attachment) that the there is a hopeful  
beginning of the DHCP configuration process of my board. But there is  
never a fitting answer from the ZyXEL which implements the DHCP-server on  
our LAN - at least as far as I see it, given my rather limited experience  
with network issues..... Has anyone out there a possible explanation  
what's going wrong here?
