Split Tunnel Routing Config Help

L1 Bithead

Looking for some help on split tunneling.

We are on PAN os 9.1.9 GP client 5.26, for our LAN we also use Cisco Umbrella to block sites.

What I want to do is when GlobalProtect connects I want all LAN traffic going through the VPN traffic, and all Internet traffic from the client going through their end, not the VPN

When I try and configure split tunneling on my gateway I follow the steps in the Split Tunneling doc, I include all my local LAN subnets in X.X.X.X/24 notation. In the Exclude I put 0.0.0.0/0

However when I connect and test with a known blocked site, I still get a blocked message. Looks like internet requests are still going through the GP client and our local LAN internet connection.

I am not sure what I am doing wrong here. Any one have any ideas?

Thank you in advance.

OK, so I removed the 0.0.0.0/0 and I checked that box.

Internet Traffic is still trying to go through the firewall. Like I mentioned above, we use Cisco Umbrella. So prior to me putting that check "on" traffic would go through the firewall then hit Cisco Umbrella and be blocked. Now when I do it I get one of our firewall blocked screens, not a Cisco Umbrella block screen

Regarding no access to local cal net.. Well that was my understanding but with the config i posted i am able to admin my local router...

Ok are you refreshing GP after updating tunnel settings.. and can you post here split tunnel settings.

Also can you post a route print output...?

L1 Bithead

Yes I disconnect, and I go into my local user app data folder and delete certs etc.

Apologize for the long route print, we need multiple networks available to our users via vpn

apologies  @Gareth.Doyle . the access to local network does need to be allowed when using windows.  Not needed though for IOS.

 

@Dan_Swartz 

still works fine for me on windows.  screen dump below with firefox filter shows BBC traffic going via local adapter and works admin server via PAngp.

also.... you seem to have a few default routes, have you added manually to local Nic's.

you have 3 default routes and the GP tunnel has the lowest metric of 1. 

here is what I get...

I think the extra default routes are from AnyDesk. I use that to remote into that machine outside our corporate network so I can test the VPN

you need to see what is adding this route with metric 1 as this will cause default route via GP as a higher priority.

Odd, that is the IP address the Palo Alto Assigns me when I connect to the VPN
