palo alto nat across S2S VPN to reach mgmt interface

Customer had 192.168.x.x network overlapping

I needed to reach 192.168.0.82


I decided to NAT on customer side.

I sent traffic to 172.17.19.0 (This was in the VPN proxy ID)

172.17.19.0 (cust side) <> 172.16.100.0 (my side)


Now for NAT

Source Zone: VPN-ZONE (don't forget tunnel interface setup)

Destination zone: LAN

Source add: 172.16.100.0

Destination add: 172.17.19.0


Translated packet

Destination address translation

Translation type: Static IP

Translated address: N-192.168.0.0-24


Also note that mgmt interface IP config is not sync'd so you will need to get your IP's allowed under 

device > setup > interfaces > management > permitted IP addresses
