NAT Loopback - Hairpin NAT

[Thabo]

Good Day

We are trying to do allow hairpin NAT for our Mitel Voice system. We want our devices on the inside network to be able to reach the Mitel device, which is on the internal network, by its Public IP Address.

I have attached topology of the environment.

Tried sk110019 - not coming right

Can you give an example of how you did the nat rule?

Here's what a Hairpin NAT rule is supposed to look like: https://community.checkpoint.com/t5/Security-Gateways/Traffic-flow-in-between-C-to-S-via-Firewall-Ho...

Just to make sure I understand, do you want something on the 5.0/24 network to hit 5.5 via 161.30.141.1.12? Do you need to hide the client's IP addresses (or, more precisely, can you?)?
