Ok I have a wireless interface ath0 and a wired re0 interface. I would like to have hostapd running on the wireless interface and allow access to the wired network also. For the most part I have this working on most systems with one exception, one of my clients cant connect I am getting "deauthenticated due to local request" in my logs, and another windows machine had the same issues until I updated the wifi driver to the latest version which solved the problem on the win machine. Here is the error I am getting wlan0: STA 00:09:2d:4b:21:a0 IEEE 802.11: associated Dec 4 09:40:23 gateway hostapd: wlan0: STA 00:09:2d:4b:21:a0 IEEE 802.11: deauthenticated due to local deauth request Dec 4 09:40:23 gateway hostapd: wlan0: STA 00:09:2d:4b:21:a0 IEEE 802.11: deassociated I also don't know ifs right to assign an ip to a bridge or not, maybe someone can look at this and make some suggestions Cause I am all googled out or ideas. > ifconfig -a re0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=3899<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST, WOL_MAGIC> ether 90:fb:a6:ed:74:a6 inet 192.168.0.3 netmask 0xffffff00 broadcast 192.168.0.255 media: Ethernet autoselect (1000baseT <full-duplex>) status: active ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 2290 ether 00:c0:ca:1f:4a:d7 media: IEEE 802.11 Wireless Ethernet autoselect mode 11g <hostap> status: running plip0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> metric 0 mtu 1500 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 options=3<RXCSUM,TXCSUM> inet6 fe80::1%lo0 prefixlen 64 scopeid 0x9 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 inet 127.0.0.254 netmask 0xffffffff nd6 options=3<PERFORMNUD,ACCEPT_RTADV> bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether 02:b5:34:b6:3f:00 id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15 maxage 20 holdcnt 6 proto rstp maxaddr 100 timeout 1200 root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0 member: wlan0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP> ifmaxaddr 0 port 11 priority 128 path cost 370370 member: re0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP> ifmaxaddr 0 port 1 priority 128 path cost 55 wlan0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether 00:c0:ca:1f:4a:d7 inet 192.168.0.2 netmask 0xffffff00 broadcast 192.168.0.255 media: IEEE 802.11 Wireless Ethernet autoselect mode 11g <hostap> status: running ssid Gateway channel 11 (2462 MHz 11g) bssid 00:c0:ca:1f:4a:d7 country US ecm authmode WPA privacy MIXED deftxkey 3 TKIP 2:128-bit TKIP 3:128-bit txpower 22.5 scanvalid 60 protmode CTS wme burst dtimperiod 1 -dfs This is my rc.conf > cat /etc/rc.conf hostname="gateway.vagner.com" defaultrouter="192.168.0.1" gateway_enable="YES" sshd_enable="YES" wlans_ath0="wlan0" create_args_wlan0="wlanmode hostap" ifconfig_wlan0="inet 192.168.0.2 netmask 255.255.255.0 mode 11g channel 11" hostapd_enable="YES" ifconfig_re0="inet 192.168.0.3 netmask 255.255.255.0 up" cloned_interfaces="bridge0" ifconfig_bridge0="addm re0 addm wlan0" routed_enable="YES" webmin_enable="YES" winbind_enable="YES" dhcpd_enable="YES" # dhcpd enabled? #dhcpd_flags="-q" # command option(s) #dhcpd_conf="/usr/local/etc/dhcpd.conf" # configuration file dhcpd_ifaces="wlan0 re0" # ethernet interface(s) #dhcpd_withumask="022" # file creation mask inetd_enable="YES" ntpdate_enable="NO" ntpdate_enable="NO" xntpd_program="/usr/local/bin/ntpd" xntpd_flags="-A -g -N -c /etc/ntp.conf -p /var/run/ntpd.pid -l /var/log/ntpd.log" named_enable="YES" cupsd_enable="YES" and my /etc/hostapd.conf file > cat /etc/hostapd.conf ##### hostapd configuration file ############################################## # Empty lines and lines starting with # are ignored # AP netdevice name (without 'ap' postfix, i.e., wlan0 uses wlan0ap for # management frames); ath0 for madwifi interface=wlan0 # In case of madwifi and nl80211 driver interfaces, an additional configuration # parameter, bridge, must be used to notify hostapd if the interface is # included in a bridge.
