Thanks for help

Hi @ibinetwork

You want a host has access to the internet link 2?

Regards

[ibinetwork (Rafael Tavares)]

External access to one port with link2 and forwarded to a host on lan

[ibinetwork (Rafael Tavares)]

The problem is the internal host block access, the nethsever is fowarding correct, sorry guys!

[jgjimenezs (Jose G Jimenez S)]

Of course my friend, PortForward.

Please note the following:

The WAN link must have fixed ip
If the WAN link using dhcp you must create an alias to wan

@ibinetwork

The problem is the internal host block access

You want to access a host on your internal network and can not?

[ibinetwork (Rafael Tavares)]

Yes access it only port foward, problem the host is blocking external access, i am test with other host and its ok. But in this host i am not have access to verify the problem.

Check if the host has enabled some firewall?

I dont have access to this host, is a server with ERP by other company

@ibinetwork the title would be (without access to a host from the local network) and not (How to port foward to backup link)

@ibinetwork

I dont have access to this host, is a server with ERP by other company

And you want to access the ERP service?

[ibinetwork (Rafael Tavares)]

Only by IP Lan

[jgjimenezs (Jose G Jimenez S)]

@ibinetwork

Only by IP Lan

That is ; you have local access to the ERP server, but you want to access from the Internet to ERP Server too?

[ibinetwork (Rafael Tavares)]

Yes exact!

[jgjimenezs (Jose G Jimenez S)]

It’s easy, you must redirect the port to ERP Server.

Example:

Protocol ----- Origin port -------destination host ------- destination port ------ wan ip (interface)
TCP ------------- 5674 ------------ Server ERP ---------------- 1443 -------------------- ISP2

check the port used by the server ERP

A problem with this host, its only accept access from ip of lan 192.168.x.x, other ips its block.

The ERP server is on a different IP range of the local network?

[ibinetwork (Rafael Tavares)]

No, its 192.168.1.12 but on access from external ip exemple 200.1.1.1 erp server block because dont have a ip lan

[jgjimenezs (Jose G Jimenez S)]

@ibinetwork

No, its 192.168.1.12 but on access from external ip exemple 200.1.1.1 erp server block because dont have a ip lan

or

@jgjimenezs

its only accept access from ip of lan 192.168.x.x, other ips its block.

You used sNAT 1:1

Create an alias to the preferred WAN, creating a host on the firewall to the server ERP
Then you set in sNAT 1:1 the alias created for the host created

What is the name of the erp and the database?
