Thank you for your response. I agree about the information, we're 
finding it hard to get firm networking info from our customers. As 
regards errors, can you give me a little indication as to how to get 
detailed information on this? Here's my ifconfig which shows no errors 
on the interface on the UM box :

eth0      Link encap:Ethernet  HWaddr 00:15:C5:E1:10:8B
           inet addr:xxx.xxx.xxx.251  Bcast:xxx.xxx.xxx.255  		
	  Mask:255.255.255.240
           inet6 addr: fe80::215:c5ff:fee1:108b/64 Scope:Link
           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
