Inbound NAT with Port Redirection for port 443 using a single outside interface IP ?

L1 Bithead

My ISP only provides a single ip address for the outside interface via DHCP.

I would like to forward port 443 to and internal host, but Palo keeps dropping the packets.


It seems as if the device management restriction is responsible for this, but I have removed that policy from the external interface so I am not sure why this is getting filtered. See console message below.

Inbound rules are set to ANY and SSH port forwarding inbound works without any problem.

Packet drops were inspected with packet filtering so I know the packets are dropped by Palo. Packets (rx,fw,dr) increasing while no tx.

Can you share screenshot of your NAT and Security policy?

Thanks for the reply unfortunately, I couldn't share the live environment, so I labbed it out and it works well in the lab environment. Thanks for the reply though.
