Hello Lawrence,

I think to make this work, you have to specify two different pars of XAUTH credentials in ipsec.secrets.
One for your iPad and one for your Android phone.

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).
