Firewall between AP & DB servers

Garbage · **Firewall between AP & DB servers** 2004-01-07 12:11

Just wondering if it is possible to have a firewall between AP & DB servers that is on one single machine (due to budget consideration).

有人建議我用兩張網卡, and set the firewall between. But how??

Thank you so much.

我覺得應該可以...

假設 AP server / DB server 都 run over TCP/IP，裝兩張：
NIC-1 的 IP address(IP-1) 為 210.10.10.1 (public ip)
NIC-2 的 IP address(IP-2) 為 10.10.20.1 (private ip)

AP Server listen 於 IP-1 port-1
DB Server listen 於 IP-2 port-2

firewall 不論軟、硬都可，架設於 NIC-2 上，應該就可以了吧（？）

供您參考。
