M4300 ACL's

Hi spopuri
Welcome to Community!
Do you want to only allow DIP=10.3.200.40 and UDP D-Port from 27000~27009 packet fowarding on the binding port? But this is only for Client->Server direction, so what about Server->Client direction? Allow or dely? Currently your config ACL will deny all packet that from Server->Client direction, is it your expected behavior?
If you want to allow both two direction traffic, you can add one more rule that permit with SIP=10.3.200.40 and UDP S-Port from 27000~27009(need you confirm if it's match your traffic that from Server->Client), then bind this ACL to the port.

Thank you very much Retired_Member
Hello Retired_Member
I have another question, If I write ACL rules to allow only port specific traffic. Will it block all other traffic by default?
Thanks,

Yes, sure. There is one default rule that will deny all traffic at the last.
So it mean, if you want to add one rule to deny the specific traffic, you must add last rule with permit all.
