By default, IPFire controls the access of all devices on blue using MAC Address filtering. This means that all DHCP leases must be manually approved in the IPFire Web User Interface before they can access the network and gain internet access. This filtering is separate to any wireless passphrase which you have applied in IPFire or to an external a WiFi access point.
This includes external WiFi access points which may also apply MAC address filtering by default.
Example (without DHCP on
- Click Enabled".
- Click Add" and the client will be able to access the internet.
To disable MAC address filtering and allow all clients connected to blue internet access do the following on the Wireless Configuration page:
- Entering the blue subnet into the Source IP field and leave theSource MAC Address field blank
- Enter the IP of the blue network's broadcast address and the subnet mask in wp>CIDR notation. For example172.16.1.0/24 for a subnet with a range of addresses from 172.16.1.0 to 172.16.1.255
## Start rule
iptables -A CUSTOMINPUT -s 192.168.49.0/24 -p tcp -d 192.168.49.254 --dport 444 -j DROP
## Stop rule
iptables -D CUSTOMINPUT -s 192.168.49.0/24 -p tcp -d 192.168.49.254 --dport 444 -j DROP
By default, the firewall will not allow traffic from the Blue network to pass through to the Green network. If you wish to allow traffic to pass through from the Blue network to the Green network, you must create a firewall rule to allow that traffic.
