The firewall sets the SYN forwarding timeout parameter (the firewall for state detection can be set in the state table), which is much less than the timeout time of the server. When the client sends the SYN packet and the server sends the acknowledgement packet (SYN + ACK), if the firewall has not received the acknowledgement packet (ACK) from the client by the time the counter expires, it sends the RST packet to the server to cause the server to delete the half connection from the queue. It is worth noting that the setting of gateway timeout parameters should not be too small or too large. If the setting of timeout parameters is too small, it will affect normal communication. If the setting is too large, it will also affect the effect of preventing SYN attacks. This parameter must be set according to the network application environment.　　他们的车停在了人烟稀少的河边。永善的殷勤吓到了仁静，仁静急忙脱离了河边向树丛中跑去。雪上加霜的是永善的车陷进了坑里一动不能动。就在这时出现了几个看上去不太友善的男子，永善觉得氛围越来越奇怪。板栗正在各处张罗，就见洪霖带着一群书生走了进来。《闪闪的红星》是根据李心田同名小说改编。该影片讲述了在30年代艰难困苦的环境中成长起来的少年英雄潘冬子的故事。但自古民不与官斗，就算咱们告了，这些刑法也只会落到胡镇的奴仆身上。该剧是一部奇幻电视剧，讲述没有选择成为妻子或母亲的当今女性的真实生活和成功故事，将描写门户网站业界激烈的竞争故事。
