CloudAccess contains an email proxy for users with Google Apps that supports three protocols: SMTP, POP3S, and IMAPS. You must configure your L4 switch to handle these protocols. Use the following high level steps to configure the protocols for your L4 switch. For more information, see your specific L4 documentation.
To configure an SMTP protocol handler for your L4 switch:
On your L4 switch, configure a new IP group (traffic group) or use an existing group for the virtual servers in the L4 switch.
You can use this group for all of the protocols.
(Optional) Create a health monitor:
Set the health checking for the pool to TCP transaction monitor.
Set the timeout to 30 seconds.
Set the health monitor to separately monitor each node.
Create a traffic pool for the SMTP virtual server to use:
Add each appliance node to the pool using the IP address with the port.
For example: 192.168.1.14:25. The SMTP port is 25.
(Optional) Add the health monitor created in Step 2.
Select your load balancing settings.
For example: round robin or random
Set the session persistence to SSL Session ID.
Create a new virtual server:
Start the virtual server.
To configure a POP protocol handler for your L4 switch:
On your L4 switch, configure a new IP group (traffic group) or use an existing group for the virtual servers in the L4 switch.
You can use this group for all of the protocols.
(Optional) Create a health monitor:
Set the health checking for the pool to TCP transaction monitor.
Set the timeout to 30 seconds.
Set the health monitor to separately monitor each node.
Create a traffic pool for the POP virtual server to use:
Add each appliance node to the pool using the IP address with the port.
For example: 192.168.1.14:995. The POP port is 995.
(Optional) Add the health monitor created in Step 2.
Select your load balancing settings.
For example: round robin or random
Set the session persistence to SSL Session ID.
Create a new virtual server:
Start the virtual server.
To configure an IMAP protocol handler for your L4 switch:
On your L4 switch, configure a new IP group (traffic group) or use an existing group for the virtual servers in the L4 switch.
You can use this group for all of the protocols.
(Optional) Create a health monitor:
Set the health checking for the pool to Connect.
Set the health monitor to separately monitor each node.
Create a traffic pool for the IMAP virtual server to use:
Add each appliance node to the pool using the IP address with the port.
For example: 192.168.1.14:993. The IMAP port is 993.
(Optional) Add the health monitor created in Step 2.
Select your load balancing settings.
For example: round robin or random.
Set the session persistence to SSL Session ID.
Create a new virtual server:
Start the virtual server.
