As soon as I specify "passthrough" policy, my IPsec session changes to type "tunnel" from output of ipsec status. Clearly I am not specifying passthrough policy correctly.</div><div><br></div><div>1) Do I need to specify left/right for my "skip" passthrough conn? If I do NOT specify left and right for skip connection, I see the IPsec type remains transport (which is good and what I want), I do see shunted policies in "ipsec status" but I still see ping packets are encrypted.</div><div><br></div><div>Thank you for any help!</div><div>Piyush</div><div><br></div>On Monday, May 22, 2017 at 12:19:17 PM UTC-7, Noel Kuntze wrote:<blockquote class="gmail_quote" style="margin:0;margin-left:0.8ex;border-left:1px #ccc solid;padding-left:1ex"><div>Add a passthrough policy for the protocol.<br><br><div class="gmail_quote">Am 22.
