I don't know much about RAS, but is it normal that the ppp adapter is
'attached' to the 192.168.42.0 subnet?
All the rest seems all correct to me. I don't have any idea whats wrong. The
strange thing is that you said that ping from subnet1 to subnet2 works, but
not the reverse direction!

Do you have any packet sniffer available? Maybe you can verify how far the
packets are going...

subnet2 is now 192.168.43.x - changed this when I initial posted the
email.

Yes

Yes subnet hands out 192.168.1.1

Same thing - which surgestions I've missed something in RRAS somewhere
(left it to defaults)
