ISP redundancy using l3 switches and checkpoint FW

Hi All,

We have recently discovered that the vsx checkpoint firewall can't support isp redundancy so our alternative is to use l3 switches.

So two internet links are coming in and are from different isps.

ISPA-------SWA-------------FW node A

ISPB-------SWB-------------FW node B

Each FW appliance will have one link to each switch ( i was unable to draw this).

The links has to be load balanced so I was thinking of using GLBP. However for the nating aspect I am confused. Can some guidance be given for this?
