At first I was using the Captive Portal. When it was discovered Vista clients were having issues I disabled that feature.
I am using the DHCP feature. But it seems the Vista clients aren't accepting the IP. This is where I get involved by checking their network settings. I've had the Vista clients disable their IPv6 and reboot. While reviewing the logs they still won't accept an IP. I have to assign them an IP (v4) and they get access to the Internet.
Thanks!
I am plagued with this problem, I will try to give them a static IP and they still are unable to connect to the internet, I have tried the IPv6 trick with no hope.
Here is the Microsoft article explaining how to fix this on the PC end but I am not about to go through the registry with anyone.

I saw a glimpse of a fix in the mailing list but no instruction on what or how to do it. I know other routers had the same problem but with a firmware upgrade the problem is gone. I am wondering if Monowall will ever fix this.
