PPPOE interface - dynamic IP - GP Portal

When establishing a connection via PPPOE there is no possibility to select the IP ("None") assigned by ISP in the Global Protect portal configuration, only the interface, which is not sufficient for it to work. I would expect that the IP assigned by ISP is created as an dynamic address object.

To make GP work with portal & gateway, I had to create a loopback, then doing a NAT from the pppoe interface's (in my case eth1/1) ip:some other port not being 443 to the loopback:443. I had to create an additional address object where I manually had to put in the dynamic ip. I now have to amend this address object manually every time the interface ip changes. Am I missing something here or is it really this cumbersome using PPPOE?


It seems PAN is not that much interested in supporting PPPOE connections- besides this, there is also lack of vlan tagging support once the L3 interface has been set to PPPOE which many ISPs require and no option for a scheduled reconnection.

This should be work with 'None' in IP address field.

Here is my testbed (sorry, mine is dhcp client - not pppoe)





With above interface, if I configure GP as below...




The device recognizes IP address which retrieved from ISP.


admin@PA-220> debug ssl-vpn global-protect-portal

portal : gptest
portal address IPv4 : 58.156.1xx.xxx

admin@PA-220> debug ssl-vpn global-protect-gateway

gateway : gptest
gateway address (IPv4 Only) : 58.156.1xx.xxx

can you select your ip where none is listed in GP portal configuration?


I have the assumption pppoe differs from dhcp

No, if IP address grabed dynamically, it is not shown on the list.

(as I mentioned above, it works with 'None')

By the way, if you configure static-ip under pppoe setting, it shows IP address.
