Help With weird Wireless problem on AP50

SilverSurfer
Hi All

Looking for some ideas on whats wrong with my setup.

I have used the AP50 for a long time now with a Private WLAN bridged to AP LAN all working fine

Yesterday I created (added) a Public WLAN (for guest internet access) to a separate zone (wlan0)
I've added a DHCP server to Public WLAN
Masqueraded Public WLAN to WAN
Added a firewall rule to allow all from Public WLAN to any ip
Added Public WLAN to allowed networks in DNS
I've turned off (for debugging) IPS,Filtering,Visibility

When I connect my laptop to the Public WLAN SSID it connects and gets an ip address from the dhcp server. I can do an nslookup to google.com and ping google.com.
I cannot browse the web although facebook half loads the page
In a the browser google.com,slashdot.org,bbc.co.uk,ebay.co.uk won't load

Teamviewer host does connect OK
Dropbox has error "Cannot establish a secure connection"
Imap mail client connects OK (I monitor the imap server) but does not download any "messages"

I'm kinda at a loss at the moment, any ideas ?

    Do you have https scan on proxy on?
    for testing only, disable webproxy and set up a WIRELESS -> ANY -> INTERNET packet filter.
    you should see in packetfilter log the requests.

    And you have for this interface setted up a masquerading rule? See Network Protection -> NAT -> Masquerading (YOURNETWORK -> UPLINK OR WAN INTERFACE)

    How do you look for the logfiles? Webadmin logviewer? Try SSH because there is no latency.

    Instead of grepping at the command line, I usually start the relevant Live Logs and watch for activity.  In all but the Firewall log, the relevant line(s) can be copied out of the Live Log.  For the Firewall log, find the corresponding line in the full Firewall log file.
