Do you have route to net/host 192.168.165.8? If not, add route with
route add 192.168.165.8 dev ppp0
where ppp0 can be ppp1 if you use second ppp interface.
or add defaultroute option to /etc/ppp/options or on the command line for
pppd.

Can you tell IP addresses of these boxes?

Again, add route to them.

Where is output chain?
If you want routing you must enable forwarding (ipchains -P forward accept)

You have two ppp interfaces?

Add route to to 142.1.0.4
route add 142.1.0.4 dev ppp0
N.B. I didn't understood quite well your network setup and if you want better
"support" try to explain in more concise and precise way (at least for us
non-native English speakers).
