Hello,

 

post all networks that are configured, so we can exclude any networks that should not be affected. We can only suggest based on the information you give. We have no way of knowing if (and what) other subnets exist.

Hello

@aasimomerosman 
Apply that  extended ACL  I supplied, and it should provide you the restriction you are looking for.


Please rate and mark as an accepted solution if you have found any of the information provided useful.
This then could assist others on these forums to find a valuable answer and broadens the community’s global network.

Kind Regards
Paul

Friend when you have one subnet want to access and other want to deny, reverse the ACL to be 

permit VLAN"printer" VLAN4 

deny any 

this solve the complex of ACL with subnet.
