ok Here is the network diagram

Internet
     |
     |
 IP_A
[EFW]
  ip_a
     |
     |
LAN_A
     |
     |
[cisco router]
     | 
     |
LAN_B
     |
     |
ip_b[PC1]


1.I want to make PC1 be able to connect to the internet via EFW

2.I added the route for reaching LAN_B on EFW

3. I added the default route for accessing the internet on cisco router.

4.I added firewall policy which allows nods on LAN_B accessing the internet

5. The nodes on LAN_A could reach the internet.

6.I could ping EFW/ip_a from PC1

7. I also could ping PC1 with source ip  EFW/ip_a

8. But I could not ping IP_A and other  ip addresses in the internet from
PC1

9.I used command tcpdump to observe icmp packets while I ping from PC1 to
internet ip. there are always two related packets like below
      ICMP reply  Destination -> IP_A
      ICMP reply  Destination -> ip_b
  compare with ping from nodes on LAN_A , there's no 2nd ICMP reply packet.

thanks for help
