Hi all I was playing with groups… I created: 1. a group (in network/host) 2 some host with ipaddress and I assigned the host to the group. Then in the source field ,I seleced the group name in Network/Host. That works… but… If I change host, with the device MAC (not IP), the same rule DOES NOT work. do you know why? Is there any setup I have to change? thanks vincenzo ---

Hi, > [@vincenzo](#): > > but… > If I change host, with the device MAC (not IP), the same rule DOES NOT work. if I understood your rule setup correctly, this would mean the same group contains both IP and MAC addresses. I am actually surprised we support configurations like that. 🙂 Do things work well if you create a dedicated group for MAC addresses, clone the firewall rule in question, and set its source to the MAC address group previously created? Thanks, and best regards, Peter Müller ---

Hi Peter each group has been set using or all IP or all MAC. No mix at all. I re-tested: 1. I created a new host named IPAD MAC where I included the Mac addr. ![immagine](https://community.ipfire.org/uploads/default/original/2X/2/2fa5cd958df83ff0e42e6f53b7345854d6cc785b.png) 2. Then I created a new group named Test and assigned the host in point 1 ![immagine](https://community.ipfire.org/uploads/default/original/2X/2/2ac3453c7f1a01f0dcf4ea03ddbc395bdf1dc803.png) 3. in the end, I’ve changed the rule, including the group Test in source field ![immagine](https://community.ipfire.org/uploads/default/original/2X/9/9c5c8176ef6d88430c3e51f94d3bdfba074ab6dc.png) In IPAD, I put [https://192.168.1.115:4443](https://192.168.1.115:4443), but then It does not reach the page. I don’t know where to look for… Thanks for your support regards vincenzo ---
