I'm trying to configure the following access-list on my lab from the sybex book:
Create an access-list on the 2600A router to block telnet access into the 172.16.60.0 network, but still allow Hosts G and H to ping HostE.
2600A(config)#access-list 110 deny tcp host 172.16.80.3 172.16.60.0 0.0.0.255 eq telnet
2600A(config)#access-list 110 deny tcp host 172.16.90.3 172.16.60.0 0.0.0.255 eq telnet
2600A(config)#access-list 110 permit ip any any
This access-list blocked source addresses 172.16.80.3 and 172.16.90.3 from telneting into 172.16.60.0. See chapter 9 of the Sybex CCNA Study Guide for information on the wildcard configuration.
The problem is that I can still telnet from the .80.3 and .90.3 workstations.
Apply this access-list to the serial interface 0 of the 2600A router to filter the packets coming into the router.
2600A(config)#interface serial 0/0
2600A(config-if)#ip access-group 110 in
The lab is configured word for word from the book.
Any ideas as to why the access list isnt working?
