Hello All,
I am trying to configure an access control list that will block UDP port 20000 and 19999 (for some lab testing) on interface 1/0/7. When I implement the rule, it blocks ALL the traffic from the and to 172.16.37.56. Is this a bug? Or, am I implementing the rules wrong?
Here is what I did:
DellLab1 (config)#access-list TEST deny udp 172.16.37.56 255.255.255.240 eq 20000 172.16.37.36 255.255.255.240 eq 19999
DellLab1 (config)#access-list TEST permit ip 172.16.37.36 255.255.255.240 any
DellLab1 (config)#interface Gigabitethernet 1/0/7
DellLab1 (config-if-Gi1/0/7)#ip access-group TEST
DellLab1#show ip access-lists
Current number of ACLs: 1 Maximum number of ACLs: 100
ACL Name Rules Interface(s) Direction
------------------------------- ----- ------------------------- ---------
TEST 3 Gi1/0/7 Inbound
I would appreciate any hints on how to set this up!
Thank You,
