您好，请知：
可以使用ACL限制。
以下是参考命令：
acl basic 2000
rule 0 permit source 192.168.1.1 0
quit
ssh server acl 2000
telnet server acl 2000
或
user-interface vty 0 4
acl 2000 inbound
quit

user-interface vty 0 4 acl 2000 inbound authentication-mode scheme protocol inbound ssh 这样配置了，但是dis log还是有很多ssh尝试登陆的，只是被拒绝了，这样大量ssh工具的时候，路由器的性能很受影响，怎么能完全让外网无法ssh尝试呢？ %Apr 2 12:22:48:187 2022 MSR2600 SHELL/5/SHELL_LOGINFAIL: SSH user failed to log in from 45.125.65.31 on VTY0 due to IP restriction.. %Apr 2 12:27:37:238 2022 MSR2600 SHELL/5/SHELL_LOGINFAIL: SSH user failed to log in from 104.248.125.146 on VTY0 due to IP restriction.. %Apr 2 12:33:28:210 2022 MSR2600 SHELL/5/SHELL_LOGINFAIL: SSH user failed to log in from 179.43.167.74 on VTY0 due to IP restriction.. %Apr 2 12:49:05:996 2022 MSR2600 SHELL/5/SHELL_LOGINFAIL: SSH user failed to log in from 83.97.20.34 on VTY0 due to IP restriction.. %Apr 2 12:59:34:060 2022 MSR2600 SHELL/5/SHELL_LOGINFAIL: SSH user failed to log in from 112.132.249.164 on VTY0 due to IP restriction.. %Apr 2 13:06:40:700 2022 MSR2600 SHELL/5/SHELL_LOGINFAIL: SSH user failed to log in from 45.125.65.126 on VTY0 due to IP restriction.. %Apr 2 14:22:59:315 2022 MSR2600 SHELL/5/SHELL_LOGINFAIL: SSH user failed to log in from 164.92.210.62 on VTY0 due to IP restriction.. %Apr 2 14:35:42:154 2022 MSR2600 SHELL/5/SHELL_LOGINFAIL: SSH user failed to log in from 124.222.17.122 on VTY0 due to IP restriction.. %Apr 2 14:35:42:191 2022 MSR2600 SHELL/5/SHELL_LOGINFAIL: SSH user failed to log in from 124.222.17.122 on VTY0 due to IP restriction.. %Apr 2 14:41:21:460 2022 MSR2600 SHELL/5/SHELL_LOGINFAIL: SSH user failed to log in from 45.125.65.126 on VTY0 due to IP restriction..
