OK, I solved #1 (D'oh!)

To make OpenS/WAN work with the WLAN GroupVPN, I turned off virtual IPs
for the WLAN. This means the WLAN IPs are now exposed to the destination
networks, whereas before only LAN IPs were. The remote VPNs were not aware
of the WLAN IP range, and therefore did not know where to send the
replies. (Double D'oh!)

I have added the WLAN range to the remote machines (I use 'firewalled
subnets' locally, so it is already included in there!) and lo and behold,
I receive replies!   :-)

Now if only #2 was as easy to fix...  :-(
