OpenVPN LAN Is still accessible

Hi.

I'm a little confused at the moment. More bewildered actually.

I setup my server1 OpenVPN server successfully this evening after some troubleshooting around remote-tls-cert

I specifically do not want to push lan to clients but i do want to redirect their internet through my router.

For some reason or another, when i login to my VPN, i can still access my NAS box on the LAN.

I can't figure it out at all. So i thought I could just do it with iptables

so i've got

iptables -A INPUT...
