Hi,

  I am testing a two nodes firewall HA configuration using uClibc 2.3.1
with "three interface" model. In leag.cfg I setup:

1 iptables and shorwall

2 kpalived (vrrp) configurared for all three interfaces:
  - in eth0 for Internet next hop and NATed DMZ IP addresses
  - in eth1 for DMZ default gateway
  - in eth2 for LAN default gateway

3 ipsec for a VPN to remote office

Now the step 1 and 2 work correctly (after removing the shorewall
builtin drop multicast) but I have a problem to setup ipsec.
The ipsec log (/var/log/auth.log) says:

  "we have no ipsecN interface for either end of this connection"

and this is correct because my ipsec.conf contains:

   interfaces="ipsec0=eth0"

If I change it to:

   interfaces="ipsec0=eth0:0"

the report is:

  "ipsec_setup: unable to determine address of `eth0:0'"

For example a LAN router that MASTER the LAN VIP has real
IP address 192.168.100.189 and VIP address 192.168.100.254

# ip addr show eth2
7: eth2: <BROADCAST,MULTICAST,ALLMULTI,UP> mtu 1500 qdisc pfifo_fast qlen 
1000
    link/ether fe:fd:c0:a8:64:bd brd ff:ff:ff:ff:ff:ff
    inet 192.168.100.189/24 brd 192.168.100.255 scope global eth2
    inet 192.168.100.254/24 scope global secondary eth2

How I can change the configuration to force ipsec to take the
alias/VIP address ?
