RV320: Cannot access several subnet through VPN


I had a simple setup using 2 RV320.

RV320 tunnel config at Site A:

Local subnet =

Remote subnet =

RV320 tunnel config at Site B:

Local subnet=

Remote subnet =

So far so good! Tunnel is established, and the 2 subnets can communicate each other successfully.

I have another switch Layer3 in SiteA, which is holding another subnet:

I want to connect SiteA RV320 to this Layer3 switch, so that I can access this subnet.

See attached (awfull!) picture.

Now I would like to be able to setup a VPN tunnel communication between Site B subnet ( and Site A new subnet (

I have tried to setup a second tunnel, with same setings as the first one except Site A new subnet.

Though it ill not work because when I try to apply ("save") the configuration, it says I cannot do that because it is "conflicting with existing Tunnel 1".

Is there a way to do this setup?

RV320: Cannot access several subnet through VPN

Hi pierrebirenbaum, thank you for using our forum, my name is Luis I am part of the Small business Support community.

I have a couple of questions for you, what firmware are you running? The last release is you can click in the version to download it.

Could you please share with us your VPN configuration? Please try to avoid including the Public addresses.

I hope you find this answer useful

RV320: Cannot access several subnet through VPN

Hi Luis,

Thanks for your answer.

I attach the config (we are in testing phase now, so no public IP are used anyway.).

I have now updated the firmware to the version you provided.

The result is the same:

When I try to create a new VPN tunnel 2 in site A with remote subnet = (i.e. the same as the one used in tunnel 1), then I get an error message when saving the config: “( is conflicting with tunnel 1. Please change it!”.

Can I avoid that error somehow, or more generally how can I implement the setup I need without using a third RV320!?

Thank you,

Re: RV320: Cannot access several subnet through VPN

Did you ever get a solution to this problem? I'm having the same issue with an RV320. FW


I have a remote site with two IP networks - and

My main site uses

I set one tunnel up between Local<->Remote

That tunnel works perfectly.

When I try to add a new tunnel between Local<->Remote, I get an error that is conflicting with tunnel 1.


I'm almost certain this is an error in the error-checking code in the GUI. I have two RV220Ws set up at two other remote sites that are configured this way and have no issues with them. I only bought the 320 because I could no longer find the 220. I had high hopes that a fix would have been released by now as I have not been able to find or develop a work around. Any help will be appreciated.
