ipsec.exe is a really old tool. ipsectool is newer, but AFAIK only works
for one tunnel. Openswan could be ported to Windows, though really only
on the newer ones with the netsh command (Vista and up I believe?)

I cannot really read this with the information hiding. If it tried to
propose with its clearly wrong. If it is not behind nat, you
prob don't have rightsubnet=vhost containing "%no" (for non nat) or if
you are behind nat, and have rightsubnet=vhost:%no,%priv, then the internal
range of the client is not part of virtual_private=

Since the phase 1 for A and B are the same, you are misled in thinking
the gateway is mistaken. When doing phase1 there is no difference, so the
connection name it picks can be iether one of the two. Once it gets to
phase 2, it should switch to the right conn.
