CodePudding user response:

This is actually doing the ACL to limit between client visit
1 routing through should be no problem!
2 mean directly on the routers use Telnet command
3 on the AR3 enable Telnet login, configured passwords, and applications in the Telnet process of acl, only allow Telnet client IP acl,
4 do ACL limit access client1 and client2, concrete is in LSW1 ge0/0/3 mouth or LSW2 0/0/2 application of ACL, ACL allows access to the Telnet client IP, are not allowed to visit client1 or client2 IP,
5 on LSW1, application of acl to allow client3 (before has been configured to allow the client client and refused to client2)
6 on LSW2 0/0/2 application of acl, want to have a refused to visit client3
7 write an acl to allow to server1 port 80,
With article 7 of the 8 a bit contradictory, but it doesn't matter, on the basis of the above acl and Telnet client IP allow server1 IP line
More than united were extended acls
