Hello Mahendra,<br>
<br>
Charon is only the keying daemon.<br>
Setting "charon.interfaces_ignore" or charon.interfaces_use"only defines the list of interfaces<br>
whose IPs are listened on by charon or not.<br>
The kernel takes care of the traffic. If you want to disable XFRM policies on an interface, then you need to<br>
disable XFRM and policy on that interface. Those are the following sysctl values:<br>
<br>
net.ipv4.conf.<interface>.disable_policy<br>
net.ipv4.conf.<interface>.disable_xfrm<br>
<br>
Set them to 1 to disable IPsec processing on that interface.<br>
<br>
