Configuring FTP Access to the Email Security Appliance
For email delivery and Virtual Gateways, each IP interface acts as one Virtual Gateway address with a
specific IP address and hostname. You can also “join” interfaces into distinct groups (via the CLI), and
the system will cycle through these groups when delivering email.

Joining or grouping Virtual Gateways is useful for load-balancing large email campaigns across several
interfaces. You can also create VLANs, and configure them just as you would any other interface (via

How AsyncOS Selects Default IP Interface
AsyncOS selects the default IP interface based on the order in which the IP interfaces appear under
Network > IP Interfaces page or in the
Network > IP Interfaces page or in the
ifconfig
CLI command. The first IP interface in the list that
resides on the subnet in question is used.
If there are multiple IP addresses configured within the same subnet as the default gateway, the IP
address with the lowest number is used. For example, if the following IP addresses are configured within
the same subnet,
address with the lowest number is used. For example, if the following IP addresses are configured within
the same subnet,

10.10.10.2/24
•
10.10.10.30/24
•
10.10.10.100/24
•
10.10.10.105/24
AsyncOS chooses 10.10.10.2/24 as the default IP interface.
Configuring FTP Access to the Email Security Appliance
Procedure
Step 1
Use the Network > IP Interfaces page or the

WARNING:
By disabling services via the
interfaceconfig
command, you have the potential to
disconnect yourself from the CLI, depending on how you are connected to the appliance. Do not disable
services with this command if you are not able to reconnect to the appliance using another protocol, the
Serial interface, or the default settings on the Management port.
