I have a DFL-260E configured to one-to-one map multiple WAN IPs to multiple DMZ IPs for multiple servers. The problem I am having is that the Mail Server uses the primary WAN IP to send mail rather than the Published IP defined in ARP/Neighbor Discovery assigned to it for use in the SAT and NAT rules.
I used this procedure setup SAT and NAT for each server in the DMZ:
Add the objects of both public and DMZ IP addresses for the server
Go to Objects -> Address Book -> Interface Addresses
Click Add
Name it eg(webpower_public_ip
IP it eg(209.218.29.10)
Click OK
Click Add
Name it eg(webpower_dmz_ip)
IP it eg(192.168.1.10)
Click OK
Create the objects in the ARP table
Go to Network -> ARP/Neighbor Discovery
Click Add
Click ARP/Neighbor Discovery
Mode = Publish
Interface = WAN
IP Address eg(webpower_public_ip)
MAC Address = default (00-00-00-00-00-00)
Click OK
Create IP rule to map server (SAT)
Go to Policies -> Main IP Rules
Click Add
Click IP Rule
Name it eg(webpower_http_map)
Action = SAT
Address Filter
Source Interface = any
Source Network = all-nets
Destination Interface = wan
Destination Network eg(webpower_public_ip)
Service – http-all
Schedule = none
Static Address Translation
SAT Translate = Destination IP
New IP Address eg(webpower_dmz_ip)
Logging and Comments
Logging = on default
Click OK
Create IP rule to allow Server NAT
Go to Policies -> Main IP Rules
Click Add
Name it eg(allow_webpower_http)
Action = NAT
Address Filter
Source Interface = any
Source Network = all-nets
Destination Interface = wan
Destination Network eg(webpower_public_ip)
Service – http-all
Schedule = none
Network Address Translation
NAT Translate = Use Interface Address
Application Control
Application Control = off
Logging and Comments
Logging = on default
Click OK
Save and Activate the Configuration
Go to Configuration
Click Save and Activate
The servers would respond to requests from the WAN but were not able to make Internet request until i added the following rule:
Name: dmz_to_wan
Action: NAT
Address Filter
Source Interface: dmz
