Port forwarding/Destination NAT

[Guest]

I have 2 NIC installed at my firewall, one of them for RED(WAN) and another one is for Green(LAN) network. Also, I have 3 PC's in green LAN side n/w.
I want to access these 3 LAN PC from WAN using their external IPs.
But can't understand how....

Already I make a NAT rules>> Incoming IP: Any Uplink--> Sevice: SMB all--> Translated to: IP--> "My 1st LAN PC IP"---> NAT--> Access from: Any.

Using this rule I can access the 1st PC but only using the Firewall's WAN IP.

But I want to access those 3 PC's separately using their own External IP. Please light up.....

Their own external IP; means do you have external IPs for each system? If yes why you are doing NAT? Why you have connected to green interface or they meant to be behind endian? What are the IP addresses of your 3 systems?

I want these 3 PC's Behind endian for service restriction. LAN IPs of those PCs are--> 192.168.1.XX but I want to access them using their external IPs which are 172.27.154.XX given by my ISP.

You have to describe in little bit more detail. But the information provided yet, you have to create rule for inbound routed traffic and allow those IPs. You also have to define host (might be) under endian firewall.

Do you have a pool of IPs assigned by your provider? To simplify you can terminate the servers on a switch and also the red interface and then control traffic through incoming routed traffic rules onto those servers..

I think "host defining" is used for local DNS...!!!
And I also configure "Incomming routted traffic" too... It is as>> Source: 172.27.154.XX--> Destination: Green---> Services: Any---> Policy: Allow...
But it still not working for me..
