Hi Cosx, You can enable HTTPS and SSH on the public facing interface i.e. the untrust interface and specify the permitted ip-address as mentioned in below link. Allowing Specific IP Addresses to Access the Palo Alto Network Device To have another layer of security you can also create a security policy from untrust zone to untrust zone and specify which ip-addresses are allowed as source and also mention the HTTPS and SSH application. This helps if you have the intra-zone policy as block i.e. untrust to untrust zone as block. Thanks, Nitesh
