Hi.


In my company we have one RV042 used to switch to WANs. When WAN1 fail, the WAN2 assumes.


In resume:

All is ok until here. But both WAN1 and WAN2 are LANs that have an specific range in IP address and one getaway each to the internet. The problem is: I want to access the LAN of WAN1 even when I use the WAN2 internet.


Detailed:

A - RV042 - Network 192.168.1.XXX (IP:192.168.1.1)

Smart Link Backup

Primary WAN: WAN1

Enable Network Service Detection: TRUE

When Fail: REMOVE THE CONNECTION


X - Router on WAN1 - Network 172.30.1.XXX (IP:172.30.1.1)

(I can't access this network when I use the WAN2, but I need)


Y - Router on WAN2 - Network 172.30.3.XXX (IP:172.30.3.1)

(I can't access this network when I use the WAN1, but I need)


Thanks for help.

Thanks for helping Syed!! The problem is: I don't want to use the load balance, I want to use only one WAN at a time. When the WAN1 fail, the WAN2 assumes and I loss the connection with the LAN 172.30.1.XXX. And vice-versa.

Dear,


Is this not exactly what you have configured on RV042



A - RV042 - Network 192.168.1.XXX (IP:192.168.1.1)

Smart Link Backup

Primary WAN: WAN1

Enable Network Service Detection: TRUE

When Fail: REMOVE THE CONNECTION


The above line says if WAN1 and WAN2 are avaiable WAN1 is active..................rite?

when WAN1 fails, remove WAN1 ( which is a subnet) so u cannot communicate with WAN1.

since WAN1 has failed WAN2 became active so you can communicate with it.


IS THAT CORRECT?


what if i say you remove everything from your RV042 and simply connect 3 subnets wan1, wan2 and the 192.168.x.x subnet. i am sure you problem will go away. u wll be able to communicate to all 3 rgadless of which wan has failed.


the logic for primary and backup wan links should be in the default routes towards each internet connection.

let say you have 2 default routes to the internet


route 1 : 0.0.0.0 0.0.0.0. via wan link 1 priority 100

route 2: 0.0.0.0 0.0.0.0 via wan link 2 priority 200


if you have the above in the RV042 what will happen that wan link1 will be primary; if it fails wan link 2 will start working. when wan link 1 resumes it will again become primary and wan link 2 will become secondary.


hope this helps.
