Actually it can. If his upstream/ISP was designed by a Cisco engineer for 
single-server-per-port hosting, then it is conceivable they use "port 
security" to restrict access.

Since Xen is a bridge by default and each DomU makes up MACs as needed, 
then they appear as multiple layer two hosts rather than just one. Thus my 
suggestion to try routing instead.

Ali, are the other addresses in your /29 netblock also for use only on 
your one server? (vips)
