Wireshark · Wireshark-users: [Wireshark-users] Capturing with no free ips

["Computer Answer" <service@xxxxxxxxxxxxxxxxxx>]

I'd like to use Ethereal/Wireshark at one of my customer sites and 
need some help. Specifically I need to setup a packet capture on a public segment with no free IPs. 
Basically, whether the capturing computer has to have an IP address on 
the same segment as the device connected to the Internet, the server 
(Novell) in this case, or whether it can capture all traffic (possibly 
as long as at least some aspects of the IP setup are similar)
