Default Problem with pf for PPPoE


I just installed OpenBSD 4.6, because I want to use nat to make a very basic firewall to split my ADSL connection between a few computers (some Linux, some Windows). I set up a very basic pf.conf with only what is necessary to use the internet. On my OpenBSD box everything work fine, I have access to any website but on my other computers only 80% of the websites work, other website like "msn.com" and "grc.com" doesn't work, it say 'Waiting for www.grc.com..." in the Firefox status bar. I tried many different settings but nothing work ... Here is my pf.conf:

ext_if = "pppoe0"

set skip on lo

match in all scrub (no-df max-mss 1440)

nat on $ext_if from !(ext_if$) to any -> (ext_if$)
For now I just want my internet access to be shared to all my computer, I'll add security rules later...

Anybody have a clue?

Thanks a lot
