Both NAT and Security Control rules are IPV4. I'm using firmware version V4.33(AAAA.0). As far as I can tell, that the latest for Zywall 110.

I changed the policy control rule as you suggested like so: I'm still unable to browse websites from my LAN. The new Email_IMAP rule is working as I expected. This one is so strange! Any other ideas?
