International ClassG06F 015/16AbstractIP network address translation (NAT) and IP filtering with dynamic address resolution in an Internet gateway system. Symbolic interface names are recognized in selected rule statements. An symbolic s-rule file is generated from these rule statements which includes symbolic interface names. During processing of a packet message, the s-rule file corresponding to the interface name in the packet message is processed, with symbolic addresses in the s-rule file resolved to the IP addresses obtained from the packet message.Other References
