ac88u dual wan / vpn

[gluemaster]

Hello,

First time poster here, been using AC88U on Merlin for awhile, and gradually to discover/use more and more of its functions. I have now come stuck on a situation hope some one here have experienced or can provide some guidance to me.


The AC88U, running merlin 384.5.

I have using the router's VPN client function successfully for some time (under single WAN mode on port 1). Under the router VPN client configuration page, I have configured for my NAS not go through the VPN, and rest all connect through VPN. Which also seems to work fine.

Recently I have added a fast 4G connection (through a 4G modem) on port 4, and configured the router to run in DUAL WAN load balancing mode.

Now my questions are:

1. Is there a way to find out which WAN connection is the VPN connection going through?
2. Is there a way to specify which WAN connection the VPN connection to go through?
   
3. I have configured IPs to go specific WAN in the DUAL WAN configuration page, and IP to go through VPN in the VPN client configuration page. How does these two work together?
   
4. My ultimate goal is: NAS not go through VPN and only use WAN port 1 connection, and all other traffic to go through VPN which go through 4G (WAN port 4) connection. How can I achieve this?

Thanks for any suggestions, if this can not be achieved by AC88U, is there any router that can do what I want?

Yes.

[Solved] Dual Wan with 1 OpenVpn Client and ability to choose which WAN to go out.
