Routing issues between OpenVPN and LAN in OpenWRT

Installing and Using OpenWrt

I am trying to set up routing between an OpenVPN network (10.8.0.0/24) and a LAN network (10.10.10.0/24) on OpenWRT. I have an OpenVPN server with the configuration:

Configuration of the OpenVPN server:

port 1194
proto tcp
dev tun
user nobody
group nogroup
persist-key
persist-tun
keepalive 10 120
topology subnet
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
push "route 10.8.0.0 255.255.255.0"
client-to-client
route 10.10.10.0 255.255.255.0 10.8.0.3
dh none
ecdh-curve prime256v1
tls-crypt tls-crypt.key
crl-verify crl.pem
ca ca.crt
cert server_kRNIy2ZLLbIrA2Yt.crt
key server_kRNIy2ZLLbIrA2Yt.key
auth SHA256
cipher AES-128-GCM
ncp-ciphers AES-128-GCM
tls-server
tls-version-min 1.2
tls-cipher TLS-ECDHE-ECDSA-WITH-AES-128-GCM-SHA256
client-config-dir /etc/openvpn/ccd
status /var/log/openvpn/status.log
verb 3

Configuration of the OpenWRT router:

LAN: 10.10.10.0/24, Router IP 10.10.10.1
WAN: 192.168.10.225/16, Gateway 192.168.10.1
OPENVPN CLIENT: 10.8.0.3
The routes on the server and router are configured, but I cannot ping devices on the LAN from the OpenVPN device.

I tried adding routes on the router and server.

That is a bit ambiguous there are two OpenVPN devices one OpenVPN server and one OpenVPN Client.

It can help if you show us the configs from Server and from Client, so please connect to your devices 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:

ubus call system board
cat /etc/config/network
cat /etc/config/firewall

And the OpenVPN Config of course
