Hello,
What firmware version are you on?
The OpenVPN network may not appear in the covered networks for Firewall zone on the older firmwares, but it should work. Perhaps you updated the device to the latest firmware with ‘keep settings’ option? If so, could you please try resetting the device to factory defaults and reconfigure it?
If the issue persists, could you check if the router receives pings on the tunnel interface when you ping the LAN devices? To do so, access the RUT via CLI/SSH with username ‘root’ , install tcpdump and run it on the tunnel interface:
# install tcpdump
opkg update
opkg install tcpdump
# check the name of the tunnel interface
ifconfig
# run tcp dump on that interface (replace tun_clntvp with your interface)
tcpdump -i tun_clntvp icmp
Do you see ICMP packets going into LAN when pinging from the server? Are there any replies?
Kind Regards,
