Hi all,<br><br><b>Topology</b><br>+++++++<br> eth0 eth0 eth1 VPN tunnel eth1 <br>Pc1 ---------------- -------GW ------------------------------ VPN server<br>172.31.114.230 172.31.114.231 50.1.1.239 50.1.1.227<br>
<br>I have established a VPN tunnel between GW and VPN server using Strongswan. After I established the tunnel the GW is not reachable from PC1 and ping fails. I have seen ARP requests in eth0 of GW, but its not replying for that. But if the tunnel is not there , ping is working fine. Please find my SPD rules below and let me know the reason for ping getting dropped.<br>
