Help configuration NAT on Cisco RV345P

[GBInformatics]

Hello,

Can you help me configure the NAT to have internet with my router please?

I can't do it at all with the Cisco router. I am not sure of anything. I am lost.

If it's possible to remove the WAN 2 interface with the IP address 192.168.150.x/24 that would be great.

I'm totally lost on how to configure

Wishing you a good evening

Hello, sorry I didn't notice that not all the information is in the message.

When I connect to my Acer X5 router I have Internet access.

What I have done :
- Connect the cable from the Acer X5 router to WAN 1.
- IP on interface WAN 1 is 192.168.140.1 /24
- In ‘Firewall’ I created a rule saying ‘Allow’ > ‘All traffic’ on ‘Any’ as the source interface for source addresses in the range ‘192.168.141.0’ to 192.168.146.0’.

The destination interface is ‘WAN 1’.
The destination address is set to ‘Any’.

I've enabled NAT for ‘WAN1’ and for ‘WAN2’.

Can you please help me? Have I connected the cables correctly?

@GBInformatics 

 You have  provided a lot of information but I am still confuse so I am going to ask for more. 

The topology you attached is not easy to see. 

What device is connected to your Internet gaterway? Is it the RV345 or you Acer X5 router? 

You dont need NAT on the RV354  IF the Acer X5 router is connected to the Internet gateway.   You need NAT on the Acer X5 router.

 Why do you have two routers? 

[GBInformatics]

The Acer X5 router is connected to the box.

The Acer router is used to get internet on the 5G sim if the box crashes.

The cabling is correct. Do I need the WAN 2 socket?

[Flavio Miranda]

Still not clear to me. What you call box?

 If your Acer Router is the exit to internet, you need to add the NAT on the Acer Router. 

 If you have two internet exit, bring 5G using Acer box and another internet exit you need to use wan1 and wan2 and you need to creste the NAT on cisco Router toware WAN2

[GBInformatics]

My box is the Orange livebox (internet provider). The 5G on my acer router is only triggered when the router no longer detects anything coming from the box.

[Flavio Miranda]

Then you dont need NAT on Cisco Router, only in ACER Router. 

On cisco Router Just add a static route sending everything to Acer Router 

And you need a route on the Acer Router returning the traffic to cisco Router local network.

And If couse a default route toward box.

This gives :
Network to be reached 192.168.140.0 /24
Gateway: 192.168.141.254 /24 (vlan 1)
Interface: WAN 1.

[Flavio Miranda]

No. If the network is 192.168.140.0 /24 the Gateway cant be 192.168.141.254 /24

Gateway must be some IP inside the range 192.168.140.0 /24

I mean, the Gateway for your hosts not for the Router. 

For the Router It should be the IP address on the Acer Router 

[GBInformatics]

what I mean is that to access the web interface, I need to connect to lan1, i.e. be on vlan 1. The gateway for vlan 1 is 192.168.141.254 /24

[GBInformatics]

Hello,

What I did in ‘Routing’, I put to reach the network 192.168.140.0 /24, it is necessary to pass via the gateway 192.168.140.0 /24.

This is what I understood from my research. To reach the box's 192.168.1.0 /24 network, you need to go through the gateway of the Acer router closest to the box, i.e. 192.168.140.1 /24 via the WAN1 interface of the Cisco router.

It's a 5G router, does it manage information when it comes from a subnet?

Hello,

I've done it, it's fine
