I am having an issue with an ACL? Maybe I am just being blind.
I am trying to do a named ACL to only allow telnet on a subinterface incoming on the port..
the issue is that when I intiial the telnet 1 packet goes to the IP statement the rest go to the TCP statement.. This means when I just use the IP statement it works but when I remove it the telnet doesnt work. results below.. any idea what the packet is I am missing.. thanks
I see two different named ACLs here: "telnet" and "ScarlettIN"
if the machine you're trying to telnet into is "host 10.16.18.5" then the "eq 23" part goes after the host, not after the clients of subnet 10.32.52.16/28. The way it is written above, sixteen consecutive IP addresses running telnet server are being permitted to access a single client.
Telnet is a tcp operation, so no need to permit udp to port 23.
Take out the icmp line if you only want to allow telnet, once you are sure you can ping the telnet host.
The "permit ip" would let any tcp, udp, and icmp traffic go from the subnet to the single host machine. Take this out. You should be left with:
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
