此时前四个需求已经完成 15.5 需求五 PC2到PC4可以访问PC5PC1不行 [r2]acl 2000[r2-acl-basic-2000]rule per [r2-acl-basic-2000]rule permit sou [r2-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255[r2-acl-basic-2000]int g 0/0/2[r2-GigabitEthernet0/0/2]nat outb [r2-GigabitEthernet0/0/2]nat outbound 2000[r2]ospf 1[r2-ospf-1]default-route-advertise # PC5:203.1.1.100 此时检测PC1到PC4都能通往PC5现在做一个ACL限制流量 [r1]acl 3000[r1-acl-adv-3000]rule deny ip source 192.168.1.64 0.0.0.15 destination 203.1.1.100 0.0.0.0[r1-acl-adv-3000]q[r1]int g 0/0/0.1 [r1-GigabitEthernet0/0/0.1]traffic-filter inbound acl 3000 15.6 需求六是R2出口只有一个公网IP 前面已经配置过 15.7 test-1设备可以登录内网telnet服务器test-2不行
15.7.1 开启telnet服务 [telnet server-aaa]local-user chenhaozhensb privilege level 15 password cipher 112301Info: Add a new user.[telnet server-aaa]local-user chenhaozhensb service-type telnet[telnet server-aaa]q[telnet server]user-interface vty 0 4[telnet server-ui-vty0-4]authentication-mode aaa
检测内网设备可以进行telnet远程登录 外网设备想访问内网telnet服务器必须做端口映射才可以 [r2]int g 0/0/2[r2-GigabitEthernet0/0/2]nat server protocol tcp global current-interface telnet inside 192.168.1.98 telnet Warning:The port 23 is well-known port. If you continue it may cause function failure.Are you sure to continue?[Y/N]:y
但现在用test-1和test-2设备进行测试测试不通因为它俩不认识202.1.1.0 30网段 [test-1]ip route-static 202.1.1.1 32 203.1.1.1[test-2]ip route-static 202.1.1.1 32 203.1.1.1
测试用test-1可以Ping通202.1.1.1但不能使用telnet服务 test-1telnet 192.168.1.98Press CTRL_] to quit telnet modeTrying 192.168.1.98 ...Error: Cant connect to the remote host
出现上面的原因是上面用OSPF协议跑通内网的时候在R1上宣告的是vlan4的路由并没有telnet服务器的路由
一般情况下服务器不会加入到动态路由协议中。
上图中telnet服务器上只有直连网段的路由信息数据包回不去。所以在tennet服务器上加一条缺省路由就可以了. [telnet server]ip route-static 0.0.0.0 0 192.168.1.97 再进行测试 test-1telnet 202.1.1.1Press CTRL_] to quit telnet modeTrying 202.1.1.1 ...Connected to 202.1.1.1 ...Login authenticationUsername:chenhaozhensbPassword:----------------------------------------------------------------------------- User last login information: -----------------------------------------------------------------------------Access Type: Telnet IP-Address : 203.1.1.3 Time : 2025-02-11 14:45:43-08:00 -----------------------------------------------------------------------------telnet server# 现在test-1和test-2都可以telnet
15.7.2 最后做策略来限制test-2进行访问
[r2]acl 3000
[r2-acl-adv-3000]rule deny tcp source 203.1.1.3 0 destination-port eq 23
# 注意不能写目标地址实验要求只是拒绝test-2进行telnet服务并没有说拒绝通信只用端口号就行
[r2-acl-adv-3000]int g 0/0/2
[r2-GigabitEthernet0/0/2]traffic-filter inbound acl 3000
最后的测试 test-1telnet 202.1.1.1Press CTRL_] to quit telnet modeTrying 202.1.1.1 ...Connected to 202.1.1.1 ...Login authenticationUsername:chenhaozhensbPassword:----------------------------------------------------------------------------- User last login information: -----------------------------------------------------------------------------Access Type: Telnet IP-Address : 203.1.1.2 Time : 2025-02-11 14:47:46-08:00 -----------------------------------------------------------------------------telnet server
