Summary: Multiple VPNs through same interface?

Initial Comment:
I've been using Bering 1.0.2 for several weeks to 
maintain a VPN between two of our sites.  All has been 
working well.

This week I needed to add a new site and installed a 
Leaf firewall at the new location.  

At our main location we've using net 10.1.0.0/24 and 
have a VPN established to 10.12.0.0/24.  I want to an 
additional VPN to 10.11.0.0/24 at the new location.

I already have a conn section of ipsec.conf for our first 
site, so I've added a second configured similarly (after 
generating a host key).  Upon restarting the firewall at 
our main location I'm starting both VPNs using:

ipsec auto --up loc1
ipsec auto --up loc2

Establishing each of the VPN connections seems to 
take a little longer than normal and lists a retry is 
needed to establish the connections.  Information 
indicating the SA has been established does appear 
after the retry delay.  Using "ipsec look" I'm seeing that 
both VPNs are setup via ipsec0.  ip route also indicates 
both VPNed nets are using ipsec0.

This doesn't seem correct.  Unfortunately it's the 
weekend and the two remote sites are closed.  I can't 
verify if my connections are good as I can't verify if any 
hosts behind the VPNs are powered up.  

Is it normal to have multiple VPNs on the same 
interface?  I can't seems to locate docs indicating the 
proper method of setting up multiple VPNs using 
Freeswan/Leaf.  

Thanks!
Bob
