Hi,<br>
<br>
You can try running tcpdump or Wireshark on the host with
Strongswan. If you see ESP packets spaced in time approximately as
the ping ICMP packets. If all you see is plaintext ICMP, than your
ping is not forwarded over the tunnel.<br>
<br>
Best regards,<br>

<div>I wish someone could answer my question.</div>
<div><br>
</div>
<div>I have established a VPN with another campany, they have a
gateawy with public IP and the subnet, the network behind the
gateway contains public IPs not private IPs ( 197.....),</div>
<div><br>
</div>
<div>The VPN is UP but i can't ping their network behind their
gateway.</div>
<div><br>
</div>
<div>Please is there any way to know that my ping request is
going inside the VPN Tunnel and not outside the Tunnel?</div>
<div><br>
</div>
<div>Iam using Strongswan with Centos 6.5, i have done
traceroute ip of the campany but it didn't give any thing, i
need just a commant or any thing to be sure that my ping
request is going inside the VPN.</div>
<div><br>
</div>
<div>I hope you could answer my question.</div>
