Thanks for the tip!

Actually when you click the (?) for the "Traffic Separation:" it says : "When enabled, the Guest Network settings of the main router can be synchronized with those of satellite devices. It can also separate the traffic of the host network and guest network, ensuring the security of your home network."

What does that mean when in EasyMesh/Access point mode, because I cannot obtain an IP address on the Guest Networks (central DHCP server is located on Default Gateway IP) and I suspect this setting only routes guest traffic to the WAN port or what? (I have not investigated that much since I already physically separated guests on earlier mentioned DMZ segment.

EDIT#1:

The DHCP issue might have been solved in 1.4.1 cause I get a DHCP lease when connected to the Guest Network there :-)

Still needs clarification on the separation issue.

EDIT#2:

Well i Still cannot get an DHCP IP when connected to the Guest Network on 1.4.1 so I guess you we can forget about EDIT#1. I noticed that that the DHCP request from the router (Guest Client) seems to be wrapped in a 802.1Q Virtual LAN, PRI: 0, DEI: 0, ID: 4002 DHCP request package - and that the firewall DHCP server does not respond to this?

Could someone explain how this Traffic Separtion is supposed to work for Guest Networks in EasyMesh Access Point mode?

You killed OpenVPN entirely - clients can't connect, host name on tplink dns doesn't exist. I can't even see options regarding domain setup. VPN server was the reason why I changed my old Archer to Ax55 couple of months ago :(

Is there any chance to downgrade to previous version? OpenVPN server is crutial feature.

Hi Joseph,

Correct, VPN was working perfectly until my unit received this update.

Thank you for trying to support but solution doesn't work - clients can't see my previously registered tplinkdns domain. All of them are trying to reconnect but domain is not reachable.

The whole section of VPN server look different after update - there is no domain customization etc.

Could you please advise how can I revert back to previous software? VPN server functionality is crucial for me.

Hi,

Sorry for confusing - I messed up pages.

I managed to deploy OpenVPN server once again (+ DDNS from tplikdns) like it was beofre update.

I noted that config file exported doesn't include DDNS - there is my public ip instead (changed it to my domain in Notepad).

Tested on 3 clients (Android, iOS and Windows) and it works...however looks little unstable.

On Windows I'm getting 

write UDP: Network is unreachable (WSAENETUNREACH) (code=10051)

Is it something wrong with port forwarding?
