Suppose the attacker is in an "interconnected" network (e.g. An Autonomous system? System), whose ISP restricts the input and output filtering of the attacker's network traffic, will be able to prevent this spoofing attack-if this method can be deployed to the correct location by the organization. This defense method of traffic input and output filtering will restrict some legitimate communications, such as the mobile IP triangular routing operation mode, so it cannot be widely deployed. IP Security Protocol (IPsec) also provides an excellent way to resist spoofing packets, but this protocol cannot be used due to deployment restrictions. Since it is usually impossible for the server side to require the ISP of the link initiator to implement address filtering or require it to use IP security protocols, more complex solutions are needed to resist this spoofing attack disguised as multiple addresses, which will be discussed later.Disk startup!/blow……贼人。现在还管不了那么多，这会子周浩正嚣张呢，必须处理好才是。　　子游自幼与牡丹订婚，无奈宰相嫌贫爱富，要将女儿另嫁将军之子青锋。牡丹不愿背信弃义，私会子游，鼓励他金榜题名，娶自己。田夫子忽然发现无法说下去了。
