[strongSwan-dev] Help: Issue with routing internet traffic through tunnel

We want to send all the traffic (including internet traffic) from Site A clients through the tunnel to Site B. Now Site B should forward to internet and send the response back to Site A.
Site A subnet : 10.1.0.0/24
Site B subnet : 10.2.0.0/24
[Site A client] ===internet_traffic===> [Site A router] ===internet_traffic===> || TUNNEL || ===internet_traffic===> [Site B router] ===internet_traffic===> [WEBSITES]
I have configured Site A’s right subnet with 0.0.0.0/0 subnet and the internet traffic is sent to Site B through tunnel.
I can see packets (ICMP echo request in the below log) coming to Site B's router but there is no reply packet.
06:46:17.970356 IP 10.147.30.243 > 10.147.30.244: ESP(spi=0xce80ace9,seq=0x3a), length 132
06:46:17.970356 IP 10.1.0.5 > 22.214.171.124: ICMP echo request, id 30485, seq 9, length 64
I suspect that IPSec is not forwarding the packets from Site B, Can you please suggest a way to forward traffic to internet using IPsec.
