Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version:

I've been struggling with this for a couple days now and hope someone has an idea on how to resolve it. There's plenty of documentation online regarding setting up OpenVPN on Omada routers, but I haven't seen much about restricting VPN to specific devices on specific subnets. 

 

I need only one device from one VLAN to utilize the VPN client: It's on VLAN 5, subnet 192.168.5.0, device IP 192.168.5.22. This VLAN/subnet is for wireless clients and the AP is an EAP610. 

 

The issue: All devices on 192.168.5.0 subnet are using the VPN connection despite the changes I've outlined below. I'm on the latest firmware. 

 

So far I've tried the obvious of setting "Local Address" to 192.168.5.22 in OpenVPN client settings. When that didn't work, I attempted policy-based routing: 

 

1) Created service types for OpenVPN ports and protocols TCP 443 and UDP 1194:

6768bdde2d2141039a064b0c3a2227e7

 

2) Created an IP group containing 192.168.5.22 only. 

 

3) Created policy-based routing policy:

addb68f522014acc9ca7476dc41252c8

 

Any help is appreciated!

I don't quite understand what you mean but show a screenshot of the VPN configuration then maybe,

policy route you can't use on OpenVPN so you can forget about it, same with other routing.

  @MR.S That is what I was wondering: If traffic from only one IP could be routed/sent through OpenVPN (what I want), or if it would have to be the entire subnet.

 

VPN works fine, but all devices on the 5.0 subnet end up using VPN, which is what I don't want. Tried setting OpenVPN as shown below, then setting up policy routing. Also tried putting the IP of the only device I want on VPN in "Local Network" field below. Either way, all devices on 5.0 subnet end up using VPN.
