DFL的技術參考文件相當的少,沒用過的話很多基本設定可能也設不起來.
剛好手邊有台之前買來測試的DFL-260E,不太好設,試了2小時才抓到訣竅.

我用這個例子的設定供您參考,
假設要另一個wan ip-172.24.28.200,做NAT對應到內部web server-192.168.10.3

1.要先設定wan端隊另一個wan ip-172.24.28.200的arp reply.
在web管理介面,到Network > Interface and VPN > APR/Neighbor Discovery
加上另一個wan ip,

2.建立一條NAT規則和防火牆規則
在web管理介面,到Policies > Main IP Rules,
先新增一條SAT rule,在SAT規則後面再新增一條allow access的rule.

既然是「企業版」的，打客服看看嚕！

Mult map ip

Web Interface
First create a SAT rule:

1. Go to: Policies > Add > IPRule
2. Specify a suitable name for the rule, for example SAT_HTTP_To_DMZ
3. Now enter:
   • Action: SAT
   • Service: http
   • Source Interface: wan
   • Source Network: all-nets
   • Destination Interface: core
   • Destination Network: wan_ip
   • SAT Translate: Destination IP
   • New IP Address: 10.10.10.5
4. Click OK
   Then create a corresponding Allow rule:
5. Go to: Policies > Add > IPRule
6. Specify a suitable name for the rule, for example Allow_HTTP_To_DMZ
7. Now enter:
   • Action: Allow
   • Service: http
   • Source Interface: wan
   • Source Network: all-nets
   • Destination Interface: core
   • Destination Network: wan_ip
8. Under the Service tab, select http in the Predefined list
9. Click OK
