M4300 ACL's

Hello,

 

I would like to create an ACL on the web interface to allow traffic from client to licensing server on a particular port.

 

Please see the attached screenshot and let me know if it is right?

 

Thanks,

Sravan

    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.

     

    Regards,

    Eric

        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,
