Abstract
A method and a system for using a network switch, such as in a gateway, to route frames between network segments are disclosed. Frames from one network segment can be provided to one of a plurality of ports of a network switch. The network switch provides the frames to a processor, whereupon the processor performs any higher-level processing of the frames, such as Internet Protocol Security (IPSec) or network address translation (NAT). After any applicable modification of the frame the processor provides the modified frame back to the network switch for output on a port associated with a network segment that includes the intended destination of the frame.
