ssl virtual ip as the destination ip the client port as the source port and port 80 as the destination port the ssl accelerator device will also send seq ack to the web switching layer the switching layer will forward the decrypted data to tcp port 80 identifying the client ip as the source ip port the switching port as the source port the destination ip as real server 300 ip address and the destination port as port 80 the switching layer will then translate the destination ip address to be source ip address source ip address to the client ip address the destination ip address to the real server ip address and the source port to the real switching port the destination port will be 80 and the http 80 request will be forwarded to server 300 the server will respond the http 80 response indicating that the destination ip is the client ip the source ip is the real server ip address the destination port is the web switching port the source port is port 80 and the appropriate seq ack switching layer will forward the http 80 response to the ssl accelerator device substituting for ip the virtual ip assigned to the server 300 by the ssl accelerator device substituting for the data for the client port and the source port equals 80 with the appropriate seq ack once received by ssl accelerator device the ssl accelerator device will encrypt the a data for port 443 assign the source ip as the virtual ip the destination ip as the client 100 ip the destination.
