Could we see more of the network topology please?

Can you do on both machines:
/bin/netstat -rn

/sbin/ifconfig

If you don't mind, it might be easiest to copy your filewall
rules so we can see them.  As root,
/sbin/iptables -L -v

If you are concerned with security and sharing your public IP address, 
may I suggest changing the public IP address ranges to something else, 
like xxx.xxx.xxx.0, yyy.yyy.yyy.0, etc, in the output. 

Another question...if you have multiple ethernet devices,
which device is 192.168.1.60 connected to?
