HI,
I have two ISP link terminated on single router.
But in present scenario we are using only ONE Link.
so it is look like --> ISP1--> Router--> Firewall--> Network Switch.
here we use dynamic natting on firewall.
All IPs used here are public IPs.
Now the requirement is We want it to load balance internal traffic to two links, so how we can achieve this.
We have multiple IP ranges in internal network and used VLAN and all these IPs natted (PAT) on firewall and then traffic goes to router internal interface (configured public IP) from Firewall interface(configured public IP).
Now if we have Second ISP now only configured router WAN interface.
What are the steps to achieve the load balancing.
Thanks in Advance

Just to confirm, your public IPs are yours, not from your ISP, correct? (I didn't think IANA allocated less than /24s.)
If you're using a default route, then as mentioned on my first post, it may be as simple as adding a second default route, although I cannot confirm the workings of your HP router.
For dynamic routing you would normally take Internet routes (all routes or partial routes) from both your ISPs usually using BGP. Of course, taking two full copies of all Internet routes demands a router capable of handling that. Again, I cannot comment on your HP router.
Further, I think it debatable how much benefit you'll obtain taking full Internet routes from both ISPs. Partial Internet routes might be more effective, but for either, BGP is going to just provide number of AS hops, with closest being better, but without accounting for actual path bandwidths.
