<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am facing one problem in Strongswan IPSEC tunnel . Can you please help me to resolve it.</p>

<p class="MsoNormal">I am using <span style="background:yellow;mso-highlight:yellow">
IPV6 over IPV4 strongswan IPSEC tunnel</span> between Access point and security gateway. Tunnel
<span style="background:yellow;mso-highlight:yellow">got established.</span> Access point got “virtual IPV6” address from security gateway via IPSEC tunnel. Access Point already got another one global SLACC IPV6 address from Broadband router. I can able to
ping security gateway’s IPV4 address as well as can able to ping IPV6 address of Virtual IPv6’s peer via IPSEC tunnel</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Problem is, I could not able to ping Broadband router’s IPV6 global address from Access Point, If IPSEC tunnel is present. I can able to ping broadband router’s IPV6 address ,if IPSEC tunnel is stopped.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Access point has two global IPV6 addresses. One is “Virtual IPV6 address” from security gateway via IPSEC tunnel and another one is IPV6 address from Broadband router.</p>
