[Openswan Users] ipsec0 on external interface with alias ip?

[openswan]

Hello,

I have one external interface eth0 and alias ip eth0:0 on the same
interface and "ipsec0=eth0 ipsec1=eth0:0" in ipsec.conf . In this case
everything is working fine i.e. pluto starts to listen on both ips eth0
and eth0:0 and because of that the interfaces are one physical interface
ipsec1=ipsec0 i.e ipsec1 is identical to ipsec0. Is there any way to put
alias to ipsec0 device (it takes the first ip of my external interface
eth0 and ignores the alias of this interface eth0:0) or to make it to
take and the ip alias of the external eth0 and in this way pluto to
starts to listen on both ips (eth0 and eth0:0). Do I need to modify
ipsec bash scripts to make ipsec0 to takes and the alias ip of the
external interface or the correct way is to put "ipsec0=eth0
ipsec1=eth0:0" in ipsec.conf?

Thank you in advance
