Hi,<br><br>I installed and build strongswan on my Android device and I have been trying to switch my device between 2 WLANs requiring tunnel setup on WLAN_2 but not on WLAN_1. Following diagram explains my setup. Generally the transition is smooth between the WLANs but occasionally, I encounter some mobike related issues while switching from WLAN_1 to WLAN_2.<br>
<br><font><font>Android device: StrongSwan client. Configuring the virtual IP in ipsec.conf as 192.168.3.3<br>
AP: WLAN_1: subnet <a href="http://192.168.2.0/24" target="_blank">192.168.2.0/24</a>: for which traffic needs to go in clear text<br>
AP: WLAN_2: subnet <a href="http://192.168.3.0/24" target="_blank">192.168.3.0/24</a>: for which traffic needs to be encrypted<br>

It seems like some race condition is occurring.<br>
Has anybody else encountered the similar problem? Any solution to this?<br><br>Thanks and regards,<br>Nitin<br><br>
