Re: Having problem tracing multiple ip addresses

[Ricardo Díez Antequera <rda () lmdata es>]

Have you used 192.168.60.200 (the subnet address) or 192.168.60.203 (the broadcast address for the subnet) for a 
device? Those addresses are reserved in your subnet and could cause errors in tcpdump engine. A /30 subnet only 
supports 2 hosts. 

Regards,
