I have a series of 10 cisco 877 and 876 routers and i want to deploy the internal firewall to deny access to everyone except the headquarters ip for management purposes.
Although i choose permit any any for my ip address i cannot access my devices.
How can i setup my routers to access via telnet, ssh and sdm???
Thanks in advance,.
Here how you can limit telnet access by ip address:
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#access-list 10 permit 10.8.10.12
Router(config)#access-list 10 permit 10.8.20.5
Router(config)#access-list 10 deny any
Router(config)#line vty 0 4
Router(config-line)#access-class 10 in
Post your config for further help.
