IPsec is connecting properly.  Perhaps the problem is that you have your 
xl2tpd with a local ip of 192.168.42.3, where the IPsec connection is 
only 192.168.4.2 (UDP port 1701).

I'm assuming that Openswan and xl2tpd are running on the same box, so 
what happens if you set local ip to match?

Or maybe check the xl2tpd/ppp debug logs at this stage.
