Hi Pete, Thank you for your help. If I use a range of address 10.1.0.1 to 10.1.0.50 using a net mask 255.255.255.0, is it ok?

You want to use a class C range for the wlan, so instead of 10.0.10.0 network, try using one of the 192.168. class C networks. It may make be best to use 2 different 192.168 networks (say 192.168.0.0/24 for LAN and 192.168.1.0/24 for the WLAN). Class A 1.0.0.0 - 127.255.255.255 Class B 128.0.0.0 - 191.255.255.255 Class C 192.0.0.0 - 223.255.255.255 Hope that helps. -- Pete Nesbitt, rhce -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
