cisco路由器NAT配置后相关PING操作问题求解?


int g0/0
ip address 124.207.70.106 255.255.255.248
ip nat outside

ip nat pool OUT 124.207.70.102 124.207.70.105 netmask 255.255.255.248
ip nat inside source list 100 pool OUT overload
ip nat inside source static tcp 192.168.100.1 80 124.207.70.102 80 extendable
ip nat inside source static tcp 192.168.100.2 80 124.207.70.103 80 extendable
ip nat inside source static tcp 192.168.100.5 80 124.207.70.104 80 extendable
ip nat inside source static tcp 192.168.100.7 80 124.207.70.105 80 extendable
ip route 0.0.0.0 0.0.0.0 124.207.70.101

从外网ping 124.207.70.106不通,ping 124.207.70.102 和124.207.70.103时而通时而不通,tracert以上2条IP在网关124.207.70.101这一跳返回TIMEOUT,求解??
