我在 GNS3 中创建了以下网络
让我解释一下设置：
- 互联网云Cloud 1连接到我的LAN而不是环回。
- R1 路由器的 F0/0 正在从 DHCP 获取 IP，我可以从 LAN 中的任何远程主机远程登录和 ping。
- R1 还配置了 SNMP 访问（公共社区字符串）
- R1 路由器的 F0/1 接口的 IP 是手动配置的。
- 我可以从 LAN 上的任何远程主机 ping 这个接口，但是 Telnet 失败。R2 路由器的 F0/0 ip 是手动配置的。这里的情况是一样的，我可以ping但是telnet失败了。R1 和 R2 之间的所有配置都相同。
再次提一下，所有接口都可以从同一 LAN 中的任何远程主机 ping，但是只有 R1 的 F0/0 可以远程登录（希望这是一个词）
我可以做一些配置更改来获得对所有接口的 telnet 访问吗？
PS：我的云网关是10.226.22.1
