We have several VLANs and would like to restrict traffic on some of them.
For one VLAN, lets say vlan 140 we would it to drop all packets except for traffic going to / from 172.30.0.49. Is this possible? If so how? Also, would users be able to obtain DHCP / DNS queries if this rule was in place?
Just like to get an understanding on how this can be done on our core using either ACL or vlan mappings.
