关于cisco地址NAT问题？...

我有82－86五个地址，83和84在cisco2621上能正常做静态NAT，但是85和86都不能正常做，做过了85和86两个地址不能够ping通，在路由器里也ping不通。不知知怎么回事？

我忘了告诉大家掩码是255.255.255.248

路由器肯定没有问题，子网掩码也没有问题，地址肯定可用，在路由上82-84都在用啊，就是85-86做静态nat不能ping通，求教啊！

有时候电信给的IP是要去头去尾的，你要问清楚了

我的IP地址：61.191.136.80－61.191.136.87

255.255.255.248

共有8个地址，去掉头尾，有5个可用阿

可以多试试,比如你把动态的nat先去掉看可不可以

去掉我怎么上网啊，版主帮帮忙啊
