That's far from enough to diagnose routing problems at host2.

Two things:
1) Try without a firewall (iptables default rules 
to "accept",  /proc/sys/net/ipv4/ip_forward to "1" and anything else).

2) Then if you can ping 20.20.20.20 from host1 *and* you can ping "the 
Internet" from host2 (say, `ping 152.46.7.81`, which is the IP for 
www.tldp.org, known to return ECHO packages) it's almost surely not a routing 
problem within host2.

Now, my bet:
Does whatever sit on the far end of your ppp link holding IP address 
10.10.10.10 know how to return packets to 192.168.0.0/24?

Cheers.
