I originally sent this email on 10/4/2013 but I got no replies, and
after a month, I still have this problem. Can anyone help?
I followed the configuration shown in the wiki for Apple IOS clients.
http://wiki.strongswan.org/projects/strongswan/wiki/IOS_(Apple)
<http://wiki.strongswan.org/projects/strongswan/wiki/IOS_%28Apple%29>
It works on one remote client (iPad). When I connect a second remote
client (Android phone) to the VPN, the iPad is disconnected
immediately. The ipsec.conf, ipsec.secrets, and strongswan.conf files
are same as the wiki example with two changes to support multiple
clients (change rightsourceip and removed rightcert).
$ diff ipsec.conf ipsec.conf.template
< rightsourceip=10.0.0.0/24
---
> rightsourceip=10.0.0.2
> rightcert=clientCert.pem
The /var/log/auth.log is attached starting from when USER #2 connects to
the VPN (at this time USER #1 is already connected and everything is
working). Thank you.
