Router RV160W VPN configuration

Just wonder if this RV160w Router support class A subnet or not, and which Cisco VPN router will support Class A subnet?

Try to configure this subnet 10.0.0.0/8 (255.0.0.0), and keep getting error.

Re: Router RV160W VPN configuration

Try to configure VPN site to site tunnel, when enter the IP address for Remote Group as below and giving me the Error message "The IP Address setting conflicts with an existing interface". I am thinking this router might not support Class A networks. any idea to configure this router to support below subnet?

***************************

Remote IP Type : Subnet

IP Address:  10.0.0.0

Subnet Mask: 255.0.0.0

Since the error message mentions conflict with a local interface can you provide information about the configuration of all of the local interfaces on your router? I am guessing that you have one or more interfaces that use subnets in that class A network.

Re: Router RV160W VPN configuration

Thank you for the additional information. In the original post you suggest that perhaps this router does not support the class A network 10.0.0.0. This output clearly shows that this is not the issue. In attempting to configure the vpn you are trying to say that the entire class A network 10.0.0.0 is remote. But the router is saying that can not be the case because this subnet of that network is local10.55.107.0. That is the conflict. Without knowing more about your environment it is difficult to know what to suggest for resolving the problem. But it seems likely that what you need is a more specific definition of what is remote for the vpn than the entire class A network.

But when I  change the remote subnet to 10.1.0.0/16 (255.255.0.0) and it is working fine. only get the error message when the remote subnet set to 10.0.0.0/8 (255.0.0.0).

Knowing that it does work when you configure the remote subnet as /16 confirms what I said in my previous response. Are you satisfied that you have a solution that works? Or is there some reason why you want the remote subnet to be /8?

 

If you really want the remote subnet to be /8 then you will need to change the subnet of the Lan on your router, perhaps using a 172.16 subnet.

Re: Router RV160W VPN configuration

I do need to set the Remote subnet as /8.  Since the remote subnet /16 has no conflict with the router subnet /24, why the Remote subnet /8 having issue. Am I doing something wrong or it is the limitation of this RV 160W router?

Re: Router RV160W VPN configuration

What you are doing does create the problem. It is not a limitation of the RV160W. When you use 10.1.0.0/16 it does not conflict with your local subnet. But when you try to say that the entire 10.0.0.0/8 is remote it is not possible to have 10.55.107/24 as the local subnet. As I suggested before you can resolve this by making the local subnet in a different network than 10.0.0.0.

Re: Router RV160W VPN configuration

Thanks Rick, would you mind to explain a little more detail how the remote subnet 10.0.0.0/8 conflict with my local subnet 10.55.107.0/24?
