ISP Failover and Global Protect (Routing Issues)

computersupport — Mon, 09 Jul 2012 17:53:51 GMT

Hello All,

I have a pretty simple setup here - single PA-2020 with dual ISP's (One Virtual Router). We're also using Global Protect (SSL VPN only) currently. I seem to have an issue that I cannot sort out.

ISP failover works great through the use of PBF. All inbound services (policies and NAT continue to function) just fine...but here's the kicker.

Through the use of PBF routing all Internet bound traffic out my primary ISP, I should NOT (in theory) need a static route in my VR for this as PBF is checked first. BUT - when this static route is removed, my Global Protect users can no longer connect to the firewall. Adding this static route back with a LOWER metric than the route for my secondary ISP fixes the issue. Obviously you can see where this can cause an issue when failed over to my secondary ISP (Primary ISP's default route has a lower metric and will attempt to be used first even though the route is disconnected).

All I'm trying to do is setup something similar to a very basic IP SLA from the Cisco world. I find it odd that the PA device can't seem to handle this alongside VPN connectivity in the very same way a Cisco PIX or ASA can.

I would like to avoid using multiple virtual routers if possible - any help would be appreciated!
