DHCP Relay for GlobalProtect

L1 Bithead

I'm trying to setup globalprotect where once a user successfully logs in, they pull an IP from our dedicated, internal DHCP server with all the DHCP options. So essentially, setup Palo Alto for a DHCP relay for the GlobalProtect clients. I was trying to do this, but the Tunnel Interface I'm using for the GlobalProtect network doesn't have an IP and doesn't show up when trying to configure a DHCP relay. Is there anyway to do this? Thank you.

@reaper So you are saying that DHCP relay, to give a DCHP address to GlobalProtect clients, with the PA forwarding DHCP requests, is not possible at this time? 


If that's the case, is there anyway to provide proxy information for clients who do connect? That's my main reason in trying to create a relay for GlobalProtect clients. We have DHCP option 252 in our scope and have that pushing to clients with AnyConnect and was hoping to do the same with GlobalProtect. Is there anyway to push a configs or dynamically assign proxy settings to GlobalProtect clients? 


Thanks everyone for the help.

@david13holt What about using DNS for distributing the proxy settings to the vpn clients or GPOs?

(In case your clients are windows based)

Hi @david13holt

currently the dhcp for GP is not that advanced (make sure to vot e on that feature request)

 

you can have a wpad entry on your DNS that could help distribute the proxy settings, instead of dhcp option 252

Hello,

The IP adress you need is for the actual DHCP server and not the tunnel interface.

In addition to this you will need the policies that allow the DHCP traffic to go betweenthe VPN zone and trust zone if you have them.

 

Hope that helps.

Does this really work for global protect clients? I thought this is not supported ... as you also have to configure an IP pool in the GP gateway configuration...

Hello @vsys_remo,

I honestly dont know. I was lookign at it from the perspective of the dhcp relay setup. It'll take me some time to set this up in a lab. Maybe @reaper, knows.

 

Regards,

hi guys!

 

Ehm, as far as I know that's not possible at this time. If you have a RADIUS that supports framed-ip, you can pull an IP that way, but it will probably not include all the options you'd like:

There are currently 2 outstanding feature requests: FR 2924 and FR 4703 (so please reach out to your sales team and have them add your vote, i already added mine)
