[Openswan Users] Listen only on one interface

[Fridtjof Busse]

Hi,
I'm running Openswan 2.4.6 and it works quite well. But I would like to
limit it to only listen on one interface (eth0, which is the
defaulroute). 
Neither interfaces=%defaultroute nor interfaces="ipsec0=eth0" helped,
'netstat' still shows me that Openswan listens on all available
interfaces on port 500.
Any way to stop this?
Thanks.
