[strongSwan-dev] Problem with Peer ID same

[Jordi Casanellas]

Hello,

I'm have a problem with a 3 connections vpn ipsec site to site with Cisco
ASA.
The problem I have is that the client has virtual vpbox with Movistar.
In the 3 vpn the "rightid" is the same to sign

So to be able to lift the vpn I need to sign with a different ip than the
one assigned.

Currently I have it working in this way from the Cisco to the provider
"Gigas".

But I want to pass it on to strongswan

In the file configuration file.conf is the following:


---START CONFIG ---
config setup

conn client

        left=81.29.122.250
        leftsubnet=192.168.100.0/24
        leftid=81.29.122.250

        right=86.45.281.11
        rightid=217.124.116.61
        rightsubnet=192.168.202.0/24
        #Encriptacio
        keyingtries=0
        esp=3des-sha1-modp1024
        ike=3des-sha1-modp1024
        authby=secret
        keyexchange=ikev1
        rekey=no

        #lifetime

        ikelifetime=60s
        lifetime=8h
        auto=route
----- END CONFIG ----

I'm test with rightid=%any and not working
I'm test with rightid same with right parameter its working but not work
traffic and tunnel not up.

Im found this plugin duplicheck
https://wiki.strongswan.org/projects/strongswan/wiki/Duplicheck#Behavior
