Hi Sayed
With the kinda topology you have in placei would suggest to lookout for redundancy in place instead of load balancing.
If you are not having a pool of ips on your own you can have HSRP in combination with NAT which can serve the purpose of both redundancy and access to internet.
Do refer the below link for configuring up the same..

ali,
you have two things in redundancy... one is statful and other is statless...
stateful failover is to continue active flows without interruption if the master fails over to the backup.
it means here you can have your session flow is continue even though your active will goes down...
that will be more clear by the following links:
http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124cg/hiap_c/ch20/haiphsrp.htm
http://www.cisco.com/univercd/cc/td/doc/product/webscale/css/css_750/redundgd/redndncy.htm
so its all depend your need...

then you can go for normal HSRP with the NAT so it will reduce the complexity with your configuration...
static nat with HSRP

Active Router Configuration
interface fa0/0
ip address 10.10.100.2 255.255.255.255.0
no ip redirects
ip nat inside
standby 10 priority 105 preempt
standby 10 name HSRP1
standby 10 ip 10.10.100.n
standby 10 track Fa 0/1

ip nat inside source static/pool -----redundancy HSRP1
ip classless
ip route a.b.c.0 255.255.255.0 fa 0/1
Standby Router Configuration
interface fa0/0
ip address 10.10.100.3 255.255.255.255.0

ip nat inside source static/pool -----redundancy HSRP1
ip classless

ali here in ip nat command you can use the static map or nat pool whatever you are looking for... for command reference this is the link: http://www.cisco.com/en/US/products/sw/iosswrel/ps1839/products_feature_guide09186a0080087c4c.html
