I support a companies' Vodafone Business Internet connection. Connection settings are to tag the WAN port traffic with a VLAN. All outgoing traffic is tagged, but discovered none of the incoming traffic is tagged. This seems very odd to me, and thought this would contravene some RFCs.
I'm running FibreX at home, and the connection needs to be tagged VLAN 10 or else there is no data flow. I have found that none of the incoming traffic is tagged.
Is this normal/by design?
Are Vodafone playing by or with the rules?
Can a Spark or other ISP customer tell me what they're getting?
