I did follow the suggestion of adding the arp entry and the route but I am still
struck up the same problem.
After adding the following entries
1. arp -s 205.148.243.3 <mac address of the external firewall>
2. route add 205.148.243.3 10.1.3.5
it doesn't seems working. I also added the next hop inside the firewall too !!
Thanks for your time and suggestion
Jey!

Dear BASKAR,
You also need to add an arp entry for the natted address ...
arp - 205.148.243.3 <mac address of the firewall external card>
in addition u need to add a route as follows
route add 205.148.243.3 <10.x.x.x> ip of the firewall internal card

You need to add a static route on your firewall for the translated
address (205.148.243.3)to the next hop inside the firewall or to the
internal ethernet port because before translation the firewall does
internal routing.

Subject: [FW1] NAT Problem in CP-Firewall
Hello,
We have installed Checkpoint Firewall-1 in our environment. I am facing
a problem of unable to PING to the NATted address.
10.1.3.15 205.148.243.2 205.148.243.1
HOSTA ------- FIREWALL -------- ROUTER ---------- INTERNET
I have a hostA 10.1.3.15 which is on the internal network. It can ping
to the Firewall [205.148.243.2] and to the router [205.148.243.1]
without any problems.
On the Firewall I have static Address Translation for the 10.1.3.15 and
set it as 205.148.243.3
The problem is I can PING to the firewall [205.148.243.2] successfully
from the internal and external network but CANNOT ping to the static
address [205.148.243.3] either from the internal nor from the external
network. Even from the Firewall server, I CANNOT ping to the NATed
address [205.148.243.3]
I have set the NAT and rules properly.
Any help to fix this problem will be greatly appreciated!
Thanks
Jey
