TRITON AP-EMAIL interfaces (E1 and E2, or P1 and P2)
Help | V-Series Appliance | Version 8.0.x
TRITON AP-EMAIL interfaces handle traffic in to and out of the TRITON AP-EMAIL module.
 
* 
Note 
The names of the interfaces vary depending on the model of V-Series appliance.
*
On V10000, E1 and E2 are used.
*
On V5000, P1 and P2 are used.
*
Both the E1 and E2 interfaces can be used to accept inbound traffic and send outbound traffic. On V5000, use P1 and P2.
*
A typical configuration is to use E1 (P1) for both inbound and outbound traffic; E2 (P2) is not used.
*
Another option is to configure E1 (P1) to accept inbound and E2 (P2) to send outbound traffic.
*
When you need to support a large volume of outbound traffic, you can configure virtual interfaces on E1 or E2 (P1 or P2). See Email module virtual interfaces.
 
* 
Important 
On the V10000, if you use the E2 interface, the E1 interface is bound to eth0, and the E2 interface is bound to eth1. Keep this in mind when you configure TRITON AP-EMAIL.
On the V5000, if you use the P2 interface, the P1 interface is bound to eth0, and the P2 interface is bound to eth1. Keep this in mind when you configure TRITON AP-EMAIL with the Email Hybrid module.
Guidelines for configuring network interfaces E1 and E2
 
* 
Note 
On a V5000, substitute P1 for E1 and P2 for E2.
If you use both E1 and E2, and you locate them in the same subnet, then the default gateway is automatically assigned to E2 (which is bound to eth1). Ensure that outbound packets can reach the Internet.
 
IP address (E1 or E2 interface)
Required.
 
Subnet mask
Required.
 
Default gateway
Required.
The gateway must be in the same subnet as the IP address of the interface (E1 or E2) used for communicating with the Internet (outbound traffic).
If you use both E1 and E2, and you locate them in the same subnet, then the default gateway is automatically assigned to E2 (which is bound to eth1). Ensure that outbound packets can reach the Internet.
Primary DNS
Required.
IP address of the domain name server.
Secondary DNS
Optional.
Serves as a backup in case the primary DNS is unavailable.
Tertiary DNS
Optional.
Serves as a backup in case the primary and secondary DNSes are unavailable.
