Some things to play around with.
Are the nic lights blinking on 0.1 when pinging from 2?
Run tcpdump on 0.1 to see if ping gets there
ping might be getting to 0.1 but not making it back to 2/3?
# iptables -L check if firewall is not up (policy ACCEPT)
What are the results from 'netstat -rn' from all machines?
192.168.0.2 and 192.168.0.3 should point to gateway 192.168.0.1
To get across interfaces eth0 and ppp0 on 0.1
