Hope this doesn't get to the list twice - but first post hasn't appeared 
a day later.

Hi all,

I have a roadwarrior config on my laptop (roadwarrior-net in the logs),
that works very well from outside the office, via ADSL connections,
whether my laptop has a public or static IP.

However, when I connect to the Internet via my mobile phone (ppp0 in the
logs), everything works apart from openswan.  The SA comes up, but I
can't ping or do anything else via the gateway.

I've put a barf at http://static.wayforth.co.uk/ipsec_barf.  Hope
someone can shed some light on it - I'm not that familiar with the ins
and outs of ipsec, but will debug further if someone can guide me on
where to start.
