Smart Link Backup RV042G

[gmati-nesrine]

Hello ,

I am writing to inquire about the feasibility of setting up a backup IPSEC VPN tunnel using WAN2 on two

 RV042G

routers. Currently, these routers are communicating via an IPSEC VPN tunnel established over WAN1. However, our client is interested in having a redundant setup using WAN2 as a backup.

I have a couple of questions regarding this setup:

1. Feasibility of Backup IPSEC VPN Tunnel: Is it possible to configure the

   RV042G

   routers to establish an IPSEC VPN tunnel over WAN2 as a backup connection? I noticed there's an option called "Smart Link Backup," and I'm wondering if this can be utilized for this purpose.

2. Network Service Detection and Failover: Assuming it's possible to set up the backup IPSEC VPN tunnel, how does the router on WAN2 detect that the WAN1 interface on the router connected to WAN1 is down? I came across an option named "Network Service Detection." Could you provide insight into how this feature works and if it's recommended for achieving seamless failover between WAN1 and WAN2?

I greatly appreciate your expertise and assistance in clarifying these questions. Having a reliable backup VPN tunnel is essential for our client's network resilience, and I want to ensure that we implement the most effective solution.

Thank you

Do you have 2 RV in the same site ? or you connecting 2 RV  using Tunnel ?

any network diagram you have current and future one you looking to do ?

if the both the WAN Link terminating to same RV

how the smart Link work :

Smart Link Backup is a feature that allows the user to set up a second WAN in case the first one fails. This feature is used to assure that the communication between the WAN and the device is always continuous.

Hello,

the two RV are not in the same site , they connecting using tunnel with interface WAN1.

So it's possible to do another tunnel backup for the first tunnel using smart link ?
