Hi,
seems in PC2 you don't have a standard gateway defined? (check with netstat -r)
Since 192.168.10.10 and 192.168.20.10 are on different networks (according to your netmask), at least to reach 192.168.10.10  from PC2  will require routing.
Strange thing is, you don't reach 192.168.20.10  from PC2 either (??)
What does 'traceroute' on PC2 say for both n.n.n.10 addresses?
