Hi,

 

I configured a Site to Site VPN between TP-Link ER7206 and a WatchGuard Firewall.

VPN is up and access is from both networks possible. 

Now I want the access only in one direction.

How can I configure it on the TP-Link ER7206?

I think I found the solution.

 

Here is what I configured.

 

For the remote Site I configured the Network/IP-Range first under

 

-> Preferences -> IP Group -> IP Address

 

add an IP-Range or Subnet here and give it a Name (RemoteNetwork)

 

Then create a Group

 

-> Preferences -> IP Group

 

add a Group and Name it (RemoteNetworkGroup). In the "Address Name" section select (RemoteNetwork).

 

Go to "Firewall -> Access Control"

Add a new rule and give it a Name.

 

Policy: Block

Service Type: All

Direction: [WAN] In

Source: RemoteNetworkGroup

Destination: Your internal LAN (in my case "IPGROUP_Any")

Effective Time: Any

States: Select all

 

klick ok. It should work

  @PROXYTEC 

I did not run a test but I think you can try stateful ACL. Add a rule to only block TP-Link ER7206 LAN networks to WatchGuard Firewall.

 

I do not have ER7206 right now and my ER605 does not support stateful ACL...

Hi,

 

yes but I'm missing some functions to get this work.

For example I was looking at the firewall settings to set a rule

 

Deny FROM "VPN X" oder "LAN 192.168.3.0/24" TO internal LAN.

 

But I did not find it.

 

With the Access Control  Menu I can not set the source I want to.

Looks like TP-Link needs to improve here!!! For a Business VPN Router such a function should be available
