I'm almost embarassed to ask this, but I'm fairly new to VLANs so...
Test setup: I've a 3com 2924 in between our LAN and a WAP. The WAP is configured with a couple of VLANs, 668 for guest wifi, 123 for staff wifi. Imagine that there are two test PCs on the LAN, (A) has a NIC configured for guest VLAN, (B) with a NIC with no VLAN configuration. I need (A) to talk to a guest (C), and (B) to talk to staff (D).
3com WAP (C)
---- ---- ----------- /
(A)---------------| | LAN | | | v668 +<
v668 | |-------------| ( X)--v668 & v123 ----| |
| | | | | v123 +<
(B)---------------| | | | ----------- \
---- ---- (D)
What's working: (A) to (C). v668 from PC to WAP, all the way through, all switch ports are tagged '668'.
What's not working: (B) to (D). What I'm needing is for the 3com port connected to the WAP, port (X), to keep tag668 in both directions, to add tag123 to untagged outgoing, and to strip tag from incoming tag123.
Is there something fundamentally wrong with this idea? I'd really appreciate some help with this, despite it being trivial, as I just cannot get it to work.
