I have done the below configuration for NAT Load balancing for our network.
Hardware Used:Cisco 1841 Router with HWIC-4ESW Card

Now I need to do these changes as per the below requirements.
1.All the traffic with a port number(ex:2622) should go through ISP1.
2.Route particular local ip's to isp1
3.All other traffic should go through both isp1 and isp2.
Please suggest me some configuration changes .
another problem is
ISP1 has given a pool of 5 ip's for us.
is there any configuration change that can be done so that i can assign public ip address directly to the internal system without using additional devices.
