Limit Rutorrent access to local IP

[Darron]

I’ve just realised that Rutorrent is open to my domain! Whoops.
There are a couple of things I’d like to do,

1. I have two ethernet adapters, so I’d like to limit it to eth1 (192.168.0.30) so I can only access it from that local IP
2. deny WAN access, local access only.
   Any ideas how I can achieve this?
   TIA Daz

Can you share following

ip -a

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

I’ve managed to restrict access to everyone except my desktop PC.
rutorrent is still exposed, but all access is denied.

In my instance:
nano /mnt/NVMe/var/www/rutorrent/.htaccess

<IfModule authz_core_module>
<RequireAll>
    Require host dj-daz.lan
    Require ip 192.168.0.10
</RequireAll>
</IfModule>

source: Access Control for Apache 2.4 (and 2.2) | .htaccess made easy

Edit: Local IP’s only. At least I have access from my internal LAN.

<IfModule authz_core_module>
<RequireAll>
    Require ip 192.168.0.0/16
</RequireAll>
</IfModule>
