Hi!
I have at home old week Keenetic as 1st router (MAC authentication, WiFi off). And Openwrt Aruba 303rw access point connected to Keenetic.
Aruba has one "br-lan" interface with set-up Protocol: DHCP client. Wireless network setup mode as Access Point.
I want to install Wireguard vpn on access point to cover all WiFi devices.
I have instructions how to set-up wireguard vpn but in doubt how to set-up Openwrt Interface and Wireless network properly?
You’ll need to route the traffic from the WiFi through the tunnel. This means setting up new network interface in a different subnet relative to your upstream lan.
Let’s see where things currently stand:
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
ifstatus lan | grep address

(I have set-up upstream router to assign static address 192.168.1.1 to Openwrt access point)
Obviously nothing will work if wan addrwss overlaps with default LAN.
Upstream router (keenetic) has other static address 192.168.1.50 .
It assignded to downsteam Openwrt AP - 192.168.1.1.
You have 192.168.1/24 in both sides of router, so it cannot route at all.
You start with making a a Guest wifi on a Dumb AP.
Next setup a WG client the normal way.
Note that only clients connected to the Guest wifi on the dumb AP will use the VPN all other traffic will just bypass this AP and go straight to the main router
Thank you! That was very usfull for me)
It's working good for now (with small remark).
There is one strange thing. I have used dns leak test. On mobile phone it's succsesfull but on laptop it unsuccesfull (showing some dns leakage).
Surfshark has 2 dns addresses. I have set-up them in WG0, guest, lan interfaces and upstream router as well. But still showing that leakage and only on Laptop.
This?
It could be that your phone is using its private DNS and the laptop is using the router as DNS server.
You probably have set the upstream router as DNS server for your AP.
In that case the AP's DNS requests from DNSMasq do not use the VPN and you have a DNS leak.
I think there are more ways out but what you can try is to set a publicly available DNS server on your AP instead of the upstream router.
Otherwise please show the settings of the AP, please connect to your OpenWRT device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
Remember to redact keys, passwords, MAC addresses and any public IP addresses you may have:
cat /etc/config/network
cat /etc/config/dhcp
cat /etc/config/firewall
ip route show
wg show
Look like. I have re-checked on laptop with Crhome, IE, Firefox - only Firefox leaking now.
Surfshark dns almost everywhere:)

That actually looks good.
All traffic should go via the VPN including traffic from DNSMasq to
No need to set these DNS servers on all interfaces all listed DNS servers are just thrown into one resolv.conf file
Browsers and Oses often use private DNS so you might see another DNS server then the ones you have chosen but the query should go via the VPN so the geographical origin should be fine.
(Unless you are using a VPN on the client itself of course)
Some strange beheviour happens - it working normaly for 3-4 days and after that it stops transfering data. "Latest Handshake - never" , RX: 0 B (0 Pkts.) on wg0 interface.
Other interfaces and networks working good and that AP.
I have checked wireguard config on laptop app and smartphone - all fine.
It's allready happens several times. I have made cleanup with soft reset and settup all again. 3-4 days and problem repeated.
Sometimes the VPN providers servers goes down for maintenance or is overcrowded and stops responding
I am using a Mullvad a very good provider but even with them I have it occasionally, sometimes reconnecting (=restarting ) WG helps but not always.
You can use watchcat to restart the WG interface.
I use a watchdog with fail over, if one tunnel goes down the next is activated.
See: https://github.com/egc112/OpenWRT-egc-add-on/tree/main/wireguard-watchdog but that might be overkill
