Dear Nicklas,
I really look forward when your document is ready. Last night I am trying to upgrade from 1.2.3 rc 3 to 2.0 rc3 and ran in a lot of problems. I got the traffic in and out through the firewall but I can only access the Gui from the Lan side (it was a problem that I cannot access the firewall remotely). Also the firewall has DNS issues itself which cannot ping external or dns look up. But the servers behind the firewall can access SSH, WHOIS, DNS, FTP, WWW..pop…etc are all good.
So, I am now restart the whole setup from scratch instead of upgrading it and import the configuration file.
May I ask a question: On the Wan side rules, the "Lan net" is replaced to "any" ? is that how you did on yours?
