I have 3 VLANs in my network and i would like to expose two VLANs(VLAN 2 and 3) to outside and the third VLAN(VLAN 4) is for internal use only.
At the outside interface point, i plan to place a switch.
I need to configure the switch Port(to which i am connecting my network) to accept VLAN2 and VLAN3 and reject VLAN4 packets.
Does any Cisco switches provide such configuration support?
As per my understanding, one Port of a switch can be assigned with only one VLAN ID.
Please correct me if i am wrong.
