Is it possible to connect from MikroTik to GlobalProtect VPN?
There is protocol support already implemented into OpenConnect client https://www.infradead.org/openconnect/globalprotect.html and it seams it’s IPsec based which is already working from MikroTik.
If you did a search for Global Protect on the forum website and found no hits, then I suggest give it a try and let us know.
An interesting idea. If Global Protect (AFAIK a Palo Alto proprietary VPN service) is as simple as described in the article you link to, you might be able to write a script to pull down the VPN settings via HTTPS, then script the IPSec configuration on the fly. I’m not sure how authentication would work. It would take some detailed analysis and testing.
