Hi,

you cannot easily load balance with public address "inside". For this, you need BGP, and both ISP willing to route the network block you've been assigned (likely, by one ISP).

If you are OK with private addresses, you can load balance using NAT and that does not requires BGP.

Hope this helps, please rate post if it does!

Hi,

You can go with BGP. Use the 'weight' attribute to assign weights to routes (as this is single internet router). Please see the link below..
