wlan interface in firewall...

Have searched and can’t find anything…
Have a PC using a xmicro Wlan adaptor that works fine, except for
allowing services through the firewall. The interface doesn’t appear either in the network setup in yast or in the firewall interface section, and I therefore can’t get Samba or Mediatomb through the firewall. How can I allow this? (I’m sure this is obvious…)
Thanks, John.

Wireless devices do not show in the firewall. But you can use the firewall to open ports/allow services as required.

Now I’m puzzled, I see wlan0 in my firewall –> interfaces list. Can you explain that? Are there particular circumstances where wireless devices do show or do not show?


What designation does the interface have when it’s running? You can find this by running the command:

sudo /sbin/ifconfig

for example here’s my wireless device from that command:

wlan0 Link encap:Ethernet HWaddr 00:22:FA:C0:E8:0E
inet addr: Bcast: Mask:
inet6 addr: fe80::222:faff:fec0:e80e/64 Scope:Link
etc etc etc…

and wlan0 is the device, what’s yours

Similar to yours…

wlan0 Link encap:Ethernet HWaddr 00:30:95:FE:C6:76
inet addr: Bcast: Mask:
inet6 addr: fe80::230:95ff:fefe:c676/64 Scope:Link…


OK try this:
Goto Yast –> firewall –> interfaces. In the RHS click button “Custom” and in the central slot of the panel that opens. labeled “External Zone”, type the entry wlan0, then OK then Next and so on to make it stick.

Then see if it worked with this command in a console:

cat /etc/sysconfig/SuEfirewall2 | grep FW_DEV_EXT=

you should get a return showing wlan0. e.g. mine is like this:

john@suse112:~> cat /etc/sysconfig/SuSEfirewall2 | grep FW_DEV_EXT=
FW_DEV_EXT=“eth0 modem0 wlan0”

Try that

So there is. Well I never.
I have never had to configure anything in there mind you.

Thanks for putting me right:shame:
