configuration of firewall in unique way

[ameetd]

I have a firewall ASA-5510 ver 7.0 with 3 interfaces, one is connected to my internal LAN, one interface is connected to ISPs with public IP 203.27.53.112 and last is going to a router which is connected to another ISP with public IP 57.12.26.53. I am using a summarized address of 192.168.0.0/16 . my requirement is that I have 2 subnet 192.168.1.0/24 and 192.168.2.0/24. I want to send my 192.168.1.0/24 internet traffic via 203.27.53.112 and 192.168.2.0/24 via 57.12.26.53(via router).Is it possible, if yes, please guide me through.

regards

Ravi

If you want to send 192.168.1.0/24 internet traffic via 203.27.53.112 and 192.168.2.0/24 traffic via 57.12.26.53(via router) then the summarization should be disabled.If summarization is present then you will be able to send traffic only with address of 192.168.0.0/16 and sending traffic to seperate address is not possible.
