Cisco IOS routing - 內網無法連上網路

[alittleboy]

目前在使用的是專線, cisco 1841.
從外面可以連至router,並可在router裡ping 內網ip,gateway等等
從內網pc可以ping wan的ip(203.121.26.130), 但沒辦法ping到gateway-203.121.26.129.

請各位大大幫忙看看以下設定是否正確
謝謝

樓主沒有告訴router要做NAT(鵝太久沒摸C牌router了,所以要怎麼config不要問鵝),router是不會"自動"做的....BTW,拿C牌的"純"router當NAT用其實佔不到啥便宜(CPU不夠快,RAM不夠多,IOS也不是每個版本都支援NAT的),沒有特殊須求的話(主要是指接leased line),高檔一點的FW/IP sharing都比拿C牌的"純"router適用就是了....

感謝大大的協助
問題已解決.
忘了加入nat/pat.

謝謝
