Bridged with lan, wireless no longer doing dhcp

[wallabybob]

You need firewall rules on the wireless LAN interface to allow DHCP traffic. There are a number of posts in the forums giving suitable rules.

Yeah hopefully this is the correct rule set.
It used to work fine before with just wifi subnet rule, but for whatever reason something either was broken and manged to correct itself, or something was working as intended and broke itself.

Which one should it be rules or rules2?

[wallabybob]

I think the requirement for firewall rules to allow DHCP traffic on bridged interfaces was new in pfSense 1.2.3.

I think either ruleset will allow DHCP traffic. Depending on your security requirements you might want to tighten up the rules.

Just as long its not accepting anything from the wan or dmz side.

down below is my dmz rules.

you want a rule on the wifi with source of 0.0.0.0 and destination of 255.255.255.255, everything else is any (*).

@XIII:

What does it do?

[jimp]

That rule allows DHCP traffic.

DHCP traffic doesn't yet have a "subnet" it's all completely broadcast, source 0.0.0.0 destination 255.255.255.255.

So basically like this?

If wifi is bridged to LAN, there is no such thing as "wifi subnet' because wifi has no IP, it's briged. :-)

So use LAN subnet there.

[Mad Professor]

Ok changed it to this so is this correct?

What about DMZ? Do I need to do anything in there?

[jimp]

Should be OK except that you don't need the 'wifi net' rules, because of what I said before. If wifi is bridged to LAN, it has no subnet.

Thank you all, I think I'm all set. The wifi is working again and my rules are set up correctly now.
