[strongSwan] Ping is not working after establishing a tunnel in strongswan

[SaRaVanAn]

Hi All,

Topology
++++++++++
     eth0                          eth0                  eth1      VPN
tunnel                 eth1
Pc1 ---------------------------------
GW(Strongswan)------------------------------ VPN server
172.31.114.230    172.31.114.231 50.1.1.239
50.1.1.227

(strongswan)

In this topology , I replaced the GW with Cisco router instead of
Strongswan, and I tried pinging from 172.31.114.230 to 172.31.114.231 and
its working fine. But the same ping is not working in Strongswan. This
seems to a bug in strongswan. Please comment.
