Interface mgmt services (ping,ssh,https,etc..) have no response in WAN2 if the default route is WAN1

:Hi, all,

Suppose I have a following simple network architecture :

- WAN1 : (GW:

- WAN2 : (GW:

- Default Route :

In WAN1, all the interface mgmt services are workable, I can connect it from a internet address, I also can ping any internet address by orginating source address from

But all above situations are unworkable in WAN2, even I configure a PBF rule as :

- source zone : WAN2

- source address :

- destination address and service : any

- action : forwarding to

Why? and how can I resolve it? is there any workaround?

Thanks a lot,

if you cerate another VR for WAN2 it will work (management services)give default gw for that VR

I tried that before just fixed it with another VR.

You can follow this DOC for configuration:

PAN-OS 3.1 ISP Redundancy Using Policy Based Forwarding

The inherent vice of capitalism is the unequal sharing of blessings; the inherent virtue of socialism is the equal sharing of miseries.

panos, thanks a lot, it's helpful idea.

craymond, thanks a lot, ^_^

but my question isn't it, but it's a helpful document

The reason this is happening is a routing issue.  When coming in from the internet the reply packets will use the default route out of the firewall.  In your case this is set to the primary interface.  Even if you were to get two default routes active you would not necessarily be able to control which wan interface got the reply packets.

The separation into virtual routers overcomes this problem by giving each wan interface their own routing table and default route.  So the reply will return out to the internet on the ingress interface.

For this solution you do need to make sure routing is setup between your two vr as you want to use the services.  For this you may want to use policy based routing.

I have the same problem. I think that this is a big problem and need to be resolved. Because, create two VR was make my administration and the troubleshooting more complex.
