I have typical problem.
I have 2 linux boxes both connected to a switch. One having IP address starting with 203.X.X.X and the other 202.X.X.X. I can telnet form the box with IP 202.X.X.X to 203.X.X.X but can't telnet from 203.X.X.X to 202.X.X.X.
Same is the case when I try to ping.
Can anyone help me out.
