Problem with Wless and DHCP

[DamienD]

Hello,

Alix/pfsense 1.2.2 embedded

I have a problem with my wless.

I bridged LAN and WLESS, added wless rule: * Wless net ****

I see my wless network but I'm unable to obtain a ip adress from the dhcp server (working fine from the wired LAN…)

I saw: http://forum.pfsense.org/index.php/topic,11309.0.html

but I don't understand what I'm supposed to do (and the post is for an old version)

Thank you!

Change the rule to * LAN subnet ****
(since there actually is no "wless subnet")

Hello!

thank you for the quick answer!

I did that and rebooted pfsense but…. still not working :-(

Ewerything works fine if I manually assign an ip/gateway/etc… adress...

but no dhcp

Yes that's to be expected.
If a DHCP client connects he does not have an IP and thus cannot be allowed by a rule which states "only clients with such an IP are allowed".

Have you tried to start out with a * * * * * * rule?
Generally when i try to make a restrictive ruleset, i first allow everything and then start clamping down with tests between the steps.

Afaik if you add a rule with
protocol: UDP,
source: any,
sourceport: 68
destination: any
destination port: 67
above your own rule you allow traffic to the DHCP server before the client has an IP of its own.

Okay… lesson learned!

I'm by far no expert so I figured it could be bad to put a rule such as: ******

It works with the two rules:

protocol: UDP,
source: any,
sourceport: 68
destination: any
destination port: 67

and

• LAN net ****

What is the best option? the pass all only rule or the set of two rules?

thank you very much!
