Ok, I am switching my server from behind my router, to be infront of it... so that it is wide open to the world... i have my reasons for this. my question though, is about the broadcast ip. when i was behind my router, this was my settings: Code: # The loopback network interface auto lo iface lo inet loopback # The primary network interface #allow-hotplug eth0 #iface eth0 inet dhcp auto eth1 iface eth1 inet static address 192.168.0.180 netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 gateway 192.168.0.1 Now that i am infront, i have an external IP... so what should I put as the broadcast? Code: # The loopback network interface auto lo iface lo inet loopback # The primary network interface #allow-hotplug eth0 #iface eth0 inet dhcp auto eth1 iface eth1 inet static address 123.123.123.123 (outside ip) netmask 255.255.255.123 (subnet mask) network 192.168.0.0 (Not a clue here either) broadcast 192.168.0.255 (NO IDEA!!) gateway 123.123.123.1 (default gateway?) any help? i know it is prolly REALLY simple... but my brain is fried this morning.
