I set up a dedicated POP3 connection, and POP3 no longer works.
Check that the generic and dedicated servers do not share the same port. The default port
number for POP3 is 110. The dedicated server will override the generic server.
When fetching mail with Outlook Express over POP3, I sometimes get a time-out
message, giving me the option to Cancel or Wait.
The appliance needs to download and scan the entire mail message before it can start passing
it to Outlook Express. For a large message or a slow mail server, this can take some time. Click
Wait to force Outlook Express to wait for the appliance to finish processing the message.
I sometimes get two copies of POP3 mail messages.
Some mail clients do not handle timeouts correctly. If the appliance is downloading and scanning
a very large message, the client might time out while waiting for a response.
A popup window prompts you to wait for or cancel the download. If you select Cancel and try
to download again, two copies of the message might appear in your mailbox.
Physical configuration
This section discusses physical configuration issues.
I connected the appliance to the network but I cannot connect to it with my browser.
In explicit proxy mode, make sure you have connected the LAN1 adapter to your network. LAN2
is for administration only, and needs to connect directly to a laptop or computer.
My network has two appliances but I can log on to only one
If you have installed a appliance, or recently used the Restore Configuration option, two or
more appliances on your network might have the same default IP addresses.
To make sure all appliances have unique IP addresses, you can use:
• The Setup Wizard.
• The network settings.
• The Configuration Console.
System configuration
This section discusses system configuration issues.
I set up different rules for inbound and outbound traffic. When I receive email
messages or browse outside websites, the Outbound rule is triggered instead of the
Inbound rule.
Make sure that the IP address of the firewall is included in the list of outside networks.
Connections from the outside may appear to the appliance as though they were coming from
the firewall.
