请高手指点迷津，不知道我配置的网络问题出在哪

刚刚接触路由器，想简单的配置路由器共享上网，路由器一台（cisco2600，两个以太网口），局域网网段为192.168.1.0，外网帐号为：202.112.149.51   255.255.255.0    202.112.149.2\r\n我的局域网pc机的ip为：192.168.1.102  255.255.255.0 192.168.1.1 。\r\n\r\n路由器配置为：fastethernet0/0：202.112.149.51  255.255.255.0 ；  fastethernet0/1：192.168.1.1 255.255.255.0  路由器的默认网关：ip default-gateway：202.112.149.2\r\n\r\n现在的问题是：我的pc机ping 192.168.1.1 和 202.112.149.51均可ping通，但是ping 202.112.149.2网关ping不通，不能上网。（由于学校ip和mac绑定，我的路由器上的fastethernet0/0 mac已改）\r\n\r\n看看我得路由器的命令结果吧：\r\n1、sh conf\r\nUsing 793 out of 29688 bytes\r\n!\r\nversion 12.2\r\nservice timestamps debug uptime\r\nservice timestamps log uptime\r\nservice password-encryption\r\n!\r\nhostname R1\r\n!\r\nenable secret 5 $1$z57n$uOEQN9ggvyjPep586coYw0\r\n!\r\nip subnet-zero\r\nno ip routing\r\n!\r\n!\r\ninterface FastEthernet0/0\r\n mac-address 001c.2300.d957\r\n ip address 202.112.149.51 255.255.255.0\r\n no ip route-cache\r\nduplex auto\r\nspeed auto\r\n!\r\ninterface FastEthernet0/1\r\n ip address 192.168.1.1 255.255.255.0\r\n no ip route-cache\r\n duplex auto\r\n speed auto\r\n!\r\nip default-gateway 202.112.149.2\r\nip classless\r\nip http server\r\nip pim bidir-enable\r\n!\r\n!\r\nsnmp-server engineID local 800000090300000D29020000\r\nsnmp-server community public RO\r\nsnmp-server community private RW\r\n!\r\nline con 0\r\nexec-timeout 15 0\r\n password 7 1511021F0725\r\n login\r\nline aux 0\r\nline vty 0 4\r\n password 7 094F471A1A0A\r\n login\r\n!\r\n!\r\nend\r\n\r\n2、sh ip route \r\nDefault gateway is 202.112.149.2\r\n\r\nHost               Gateway           Last Use    Total Uses  Interface\r\nICMP redirect cache is empty\r\n\r\n\r\n请高手指点，谢谢各位了！！

大家帮帮忙啊，谢谢了....

ip default-gateway 是有问题的，但从来不用忘了啥问题了。\r\n建议养成用0.0.0.0 的习惯。

为什么他一定要使用NAT方式上网呢？
