摘　　要：DNS-ALG(DNS应用层网关)被设计用来使NAT-PT网关更具实用性,并围绕它设定了域名解析规则。但现有NAT-PT网关域名解析模块的设计及规则在实际使用中暴露出不适应现实复杂网络的问题。在对以DNS-ALG为核心的域名解析模块进行说明的基础上,针对NAT-PT网关域名解析模块存在的问题进行分析并提出改进方案,方案对模块设计与规则进行了修改,提高了NAT-PT网关的适应能力和使用效率。DNS-ALG module is designed to make NAT-PT devices more convenient to use. But the fact is that the use of DNS-ALG module arises new problems. Reason is its design and rules which mainly face to lab network can not fit complicated commercial network environment. Based on illustration of DNS-ALG working process, potential problems exited in domain name resolution module is analyzed and new improvements is brought forward, which makes modifications both on module itself and rules of NAT-PT environment. Tests prove that new design improves the capability of adaptation and translation efficiency.
