求助：2621XM的静态NAT出现问题

CLeon

按照正常情况配置了路由器，配置完成之后发现静态映射的一台服务器在进行数据传输时总是出现丢包的现象，表现为：从公网ping 该服务器的外部地址总是有部分超时（该服务器在别处测试一切正常），从内部Ping 其内部地址没有任何问题，请各位高人多多帮忙啊！\r\n\r\n另有一个问题，ip pim bidir-enable这条命令达到的效果小弟一直不明白，望赐教。\r\n\r\n配置清单：\r\n!\r\nversion 12.2\r\nservice timestamps debug uptime\r\nservice timestamps log uptime\r\nservice password-encryption\r\n!\r\nhostname 2621XM\r\n!\r\nenable secret 5 $1$6O$4n37RNaDWhwRCgM25sL0\r\n!\r\nip subnet-zero\r\n!\r\n!\r\nno ip domain-lookup\r\n!\r\n!\r\n!\r\n!\r\ninterface FastEthernet0/0\r\n ip address 211.10.16.114 255.255.255.252\r\n ip nat outside\r\n duplex auto\r\n speed auto\r\n!\r\ninterface FastEthernet0/1\r\n ip address 192.168.3.1 255.255.255.0\r\n ip nat inside\r\n speed auto\r\n full-duplex\r\n!\r\n\r\n\r\nip nat pool temp 211.99.16.128 211.9.16.128 netmask 255.255.255.252\r\nip nat inside source list 1 pool temp overload\r\nip nat inside source static 192.168.3.14 211.99.16.131\r\nip classless\r\nip route 0.0.0.0 0.0.0.0 211.10.16.113\r\nno ip http server\r\nip pim bidir-enable\r\n!\r\n!\r\naccess-list 1 permit 192.168.3.0 0.0.0.255\r\n\r\n!\r\nline con 0\r\nline aux 0\r\nline vty 0 4\r\n logging synchronous\r\n login\r\n!\r\n!\r\nend\r\n\r\n\r\nsh ver\r\nCisco Internetwork Operating System Software\r\nIOS (tm) C2600 Software (C2600-I-M), Version 12.2(T5,  RELEASE SOFTWARE (fc1)\r\nTAC Support: http://www.cisco.com/tac\r\nCopyright (c) 1986-2002 by cisco Systems, Inc.\r\nCompiled Fri 21-Jun-02 08:50 by ccai\r\nImage text-base: 0x80008074, data-base: 0x80A2BD40\r\n\r\nROM: System Bootstrap, Version 12.2(7r) [cmong 7r], RELEASE SOFTWARE (fc1)\r\n\r\nSystem image file is \"flash:C2600-i-mz.122-8.t5.bin\"\r\n\r\ncisco 2621XM (MPC860P) processor (revision 0x100) with 60416K/5120K bytes of mem\r\nory.\r\nProcessor board ID JPE082510HG (2367941390)\r\nM860 processor: part number 0, mask 32\r\nBridging software.\r\nX.25 software, Version 3.0.0.\r\n2 FastEthernet/IEEE 802.3 interface(s)\r\n32K bytes of non-volatile configuration memory.\r\n16384K bytes of processor board System flash (Read/Write)\r\n\r\nConfiguration register is 0x2102

东方补白

配置应该没什么问题，看看是不是线缆和接口的原因。

回楼上的，我已经将 物理线路测试过了，没有任何问题。\r\n方法是用笔记本直接连，然后ping内网和外网\r\n而且出现此问题是只有在nat的ip地址上才有的问题，其他的ip都可以正常运行
