ECMP and PBF not work

L0 Member

we have a PA-820 with dual ISP internet (ethernet 2, ethernet 3)  and  ECMP. all PC can load balancing through 2 Internet connection.

If I use PBF so PC only go out through ISP 2( ethernet 3), I see this PC cant connect to Internet any more. It seem ECMP cant work with PBF, is there any way to do this ?


this is PBF rule

Hi there,

I haven't tried this design pattern myself, but I suspect you should try enabling 'symmetric return' on the Virtual Router ECMP settings.
