Hi,
- It should not be a problem as we depend on Local-in-policies to restrict administrative access(HTTPS, PING, SSH, and others) in the interface level of the Firewall.
- Usually security policies are between the interfaces say port1 to port2. So the management communication towards the Firewall will not match.
- However when you are configuring the geo location block make sure you dont have any policy which can block this communication.
- Make sure you have some kind of alternate access to the firewall when you make this changes as a precautionary measure.
Regards,
Shiva
