I think dhcp always is untagged on ethernet by the standard as it might tell you what vlan to use maybe. At least i had such issues when trying to run a dhcp server on a cisco connected on vlan virtual interfaces

hey folks,

[sorry for the double post, looks like i posted incorrectly the first time.]


if i'm sniffing between a linksys router and a cisco swtich, and the linksys is on a vlan, shouldn't i be able to see DHCP OFFERS & REQUESTS that clients are getting from this linksys router? or does vlan tagging hid them or something?
