I just replaced my Netgear firewall with a Sonicwall TZ-205. I have been able to configure all of my required ports fine for the things that need to get through except port 443. I have tried several times manually and via the on-board wizards to configure port 443. I have an Exchange server behind the firewall. I have Iphones that have normally connected just fine through the Netgear via 443 to the Exchange. When I configure the Sonicwall my Iphones cannot connect to the Exchange server. Thanks in advance for any advice...not sure where to look to fix this.
