The other is a disguised ACK packet that responds to SYN-ACK to reach the server through firewall/proxy. This disguise prevents the TCB of the server from staying in the SYN-RECEIVED state, thus ensuring free space in the backlog queue. The firewall/proxy will stay and wait for a period of time. If the correct ACK of the connection initiator is not detected, it will pass through the disguised TCP? The RET message causes the server to release the TCB. For legitimate connections, packet flow can continue without the influence of firewalls/proxies. This method is more attractive than the above method of disguising SYN-ACK, because the firewall/agent does not need to directly participate in the connection after the legal connection is established.2005年，“城乡一体化”的浪潮席卷全国，郊区村民“老算盘”顾金银家拿到了每人四十万元的拆迁费，对于这笔不菲的数目，他的三个儿女盘算已定。老大顾前决定投资生意，老二顾后想用来还赌债，三女儿顾琴想出国深造。老算盘制造了一个晴天霹雳，使得平静的农家起了风暴：他用这笔钱在城里买了一座酒楼，三兄妹的美梦化为泡影。接下来的首要任务就是齐心协力经营好酒楼，可酒楼的经理该由谁出任？众人盘算时，老算盘又宣布一道消息：“谁拉到赞助多，谁就当这个酒楼经理”。这是老算盘给儿女们出的第一道考题。三兄妹在金钱与人生、灵魂与财富的博弈下，时时拷问着求变、求富的思想，在一次次的打磨历练中，不断攀登人生阶梯、刷新着自己的精神世界。　　而商海棠的初恋情人马静安更遭遇了家破人亡的惨痛，在恋人和亲人相继离去的双重打击之下，他落草为寇，靠着过人的智慧和毒辣，成为独霸一方的匪首，一心不择手段想搞垮鲍家，使商海棠重回自己怀抱……?
