How to configure RV130W to communicate with another router connected to RV130W's LAN port?

Please find diagram of network under descussion:

cisco RV130W router ( say R1) is used to accessing the internet (ISP connected to its WAN port).

Also we need to connect to RV130W's LAN port another router R2 (that support another subnet 192.168.0.0/24 and doesn't support dynamic routing, only static).

I connected router R2 to RV130W's LAN port a syou can see on picture.

RV130W's LAN is subnet 192.168.1.0/24 and RV130W has IP address 192.168.1.1

It's possible to ping devices in subnet 192.168.1.0/24 from subnet 192.168.0.0/24 - 192.168.0.104 can ping and access 192.168.1.106 - but not vice versa - 192.168.1.106 can't reach 192.168.0.104.

It's possible to access internet from subnet 192.168.0.0/24.

I added static route to route table in R1:

192.168.0.0    255.255.255.0   192.168.1.111 LAN interface

where 192.168.1.111 is IP of router R2's WAN port - that is port used to connect R2 to R1

But it's not possible to ping any device in subnet 192.168.0.0/24 from subnet 192.168.1.0/24

For instance, it's not possible to ping router R2 (with IP from another subnet 192.168.0.1) from cisco R1 diagnostic tool in web console.

RV130W is in gateway mode. turning it in router mode prevents accessing internet of devices from subnet 192.168.0.0/24. Cisco docs says that switching to router mode turns off NAT.

How to configure RV130W to communicate with another router connected to RV130W's LAN port?

More precisely: How to ping 192.168.0.104 from 192.168.1.106?

Thank you in advance!

 

At the moment I fount some temporary approach  - using NAT of router R2.

Essentially NAT of router R2 may cause the problem of connectivity - router R2 just doesn't suppose to route packets to its subnet  - instead it uses NAT

So, to use FTP server om 192.168.0.104 from client 192.168.1.106 from another subnet I mapped necessary ports in NAT settings to forward FTP packets arrived to port 21 to host 192.168.0.104.

In oher words routing is performed now based on ports - on NAT port mappings.

This approach has some drawbacks  - I cant select different FTP servers differentiating hosts based on IP addresses - now I should differentiate hosts using different ports - say for another FTP server I use port 2121 (not 21 that is occupied by first FTP server)

It seems I found better approach - I turned off NAT on router R2 - this was the mail reason why packets were not be routed via R2 - because it uses NAT and as far as I understand  - IP exposed by NAT is final destination for usual routing  - router in NAT mode rather maps packets to IP addresses inside NAT subnetwork than route them.

 

So I added static routed (as mentioned earlier) to router R1

 

192.168.0.0 255.255.255.0 192.168.1.111 LAN interface

 

and router R2 has following table:

Now I can communicate between two networks in both directions. And access internet also.

I know that you got this working by turning of NAT, but here's what I would have done.

 

Have/create 2 different VLANs on R2 . One for 192.168.1.0/24 and one for 192.168.0.0/24.

Changed operating mode on R2 from Gateway to Router, as long as you don't need to use WAN port on R2 for direct internet access.  (Can be found under Networking-> Routing) 

Also enabled Inter-VLAN Routing.

Assign VLAN membership to the ports under Networking->LAN->VLAN memberhip as appropriate.

Tagged/untagged access to vlan.

 

You will have to either enable RIP or ro static routes in both R1 and R2. (as you have done already.)
