Hi Mohammed,
Are you connecting 2 ISP for accessing the internet?
I haven't seen any NAT commands here. Have you already nat somewhere? If that 's for the internet then you can use 2 ways for utilizing 2 links.
#########
ip route 0.0.0.0 0.0.0.0 212.xx.xx.yy(Next-Hop)
ip route 0.0.0.0 0.0.0.0 192.168.198.29
This lets box to do load-sharing as such per-destination load-sharing.
But I would concern about this way because you are using unequal links.Box will do load-sharing for you. May be 5M-link will be used at full utilization while 20M-link be used a few bandwidth (may be).
########
You can use PBR to load-sharing which traffics you want.

If you have already nat then you may separate the traffics by using protocols(http,https,smtp etc) instead of using source ip address to route them out the interface you want.
Hopes this helps
Thot

Hi sorry to steal the thread. but i was just wondering isnt there a device call like Fat pipe or something like that , that combines links from different IP's.
how does that work??

One device I know of is a Radware Linkproof. I believe all models are Ethernet/FE/GE based, goes in between your ISP routers and your firewalls. You configure it for your ISP IP ranges, and (by default) it balances traffic between the links. It also works for incoming connections, by becoming the DNS server for inbound traffic.
