Hi,

        I am having trouble with networking between my physical host and the virtual uml host. I am using the old slip method to connect between them. I am trying to ping from 172.20.12.131 (uml) to 172.20.12.130(physical host). Ping loses all packets. Here is the output of ifconfig and route on both the machines. Can anyone point me to what I am doing incorrectly?

Thanks
Chandra
