摘　　要：基于汇文服务器的网络环境特点,运用IPFW制作一个透明网桥防火墙,对其动态规则进行分析,作出一个适合数据库长连接的规则集.另外,对oracle数据库的端口复用及连接保活进行了较为深入地探讨.实践表明:透明网桥式接入点具有隐蔽性,可避免多种攻击,可避开一般3层防火墙的NAT带给oracle应用程序的局限性.Based on the network environment characteristic of Huiwen server, we made a trans- parent bridging firewall with IPFW and analyzed its dynamic rules to get a rule set fitting the large join of database. In addition, this paper discusses port reuse and connect keeping alive of oracle database. Transparent bridging access point has concealment which avoids various attacks and limitation with normal 3 layer firewalls bring to oracle application program.
