Model: Archer AXE75  
Hardware Version: V1
Firmware Version: 1.1.6 Build 20221208 rel.72102(4555)

I have to access my customer's VPN.

He provided me the .ovpn (OpenVPN) client conf file.

 

If I use the .ovpn file directly on my PC, in a OpenVPN client, everything works fine. I can reach the remote networks and my default traffic (not for the VPN networks) goes directly to the Internet.

 

When I use the same file on my router AXE75, _ALL_ traffic goes through the VPN!!! Why?

I want that _ONLY_ the traffic towards my customer networks (which his VPN server pushes) to go over the VPN. Like my PC does.

 

Can anyone support?

  @Sunshine , thank you very much.

It did the trick ;)

 

 

BTW, is there a way to view more router conf details? Mainly the dynamic ones like routing tables, NAT table, name servers, etc.?

Some kind of CLI (even if read-only) where I could execute some ifconfig, nslookup, even ping and tracert, etc.

 

I'm checking where the traffic is going through, by using traceroute (tracert in windows) on a device connected to my LAN :P

Hello, for the routing table, you could check it on the router web interface: Advanced->Network->Routing, but I am afraid CLI etc. are not supported.

Hi, thank you very much! I did found the routing table. yes

 

 

BTW, as you were able to answer this .ovpn issue on the Archer AXE75, I do have an issue, with completely opposite behavior, on another TP-Link router (business line), the ER605 (TL-R605). I'm hopping you could provide some useful hints as well... angel

 

In this case, using the very same .ovpn configuration file I have the opposite behavior :( . No traffic over the VPN, because I have NO routes for the tunnel in the routing table!!

I only have the local VPN network (you know, no "next hop", just the network on the tunnel interface).

It seems that the router doesn't learn the routes pushed by the VPN server!

 

Do you have any ideas that you could share? :)

Thanks in advance anyway.

Hello, do you mean the .ovpn configuration file used on ER605 also added the 4 lines I sent you?

If you remove the 4 lines for ER605, will it work as expected? If it still doesn't work properly, it is recommended to start a new thread on the business community.

Hi  @Sunshine ,

 

I tried the pristine version (without your 4 lines) first. It didn't work.

Then I tried the version with the 4 lines. It didn't work either :(

 

I already started a thread on the business comunity.

 

Thank you for your time :)
