I have a DSL-2770L and want to configure VLAN, however, the configuration seems much different than normal setup of VLAN.

I have an AE, that connects to Port 3. It tags the Guest network with 1003, and leaves the main network untagged.

That means on the DSL-2770L, it should accept VLAN 1 (default/untagged) and 1003.

How should I configure this router?

Link>Welcome!

• What Hardware version is your modem? Look at the sticker under modem.
• Link>What Firmware version is currently loaded? Found on the modems web page under status.
• What region are you located?

Is there any usable information in the user manual about this?

Thanks for replying.
Can't get to the device - it is on the other side of the world to me at the moment :/
Firmware is AU_1.03 - but the latest change log doesn't mention changes to VPN.
Located in Australia.

You may need additional help as well.

Have someone install team viewer at the site where the modem is on a PC that way you can remote in to the router via pc and configure it.

I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email.
Let us know how it goes please.

Hi,

you would have to configure Port3 both

• VID 1, Tx Tag unchecked
• VID 1003, Tx Tag checked

I guess the DSL-2770L doesn't support VLAN-trunking (allowing several VLANs plus a native VLAN at a single physical port) - otherwise the configuration GUI would offer an opportunity to do so.

I almost agree with you, but - isn't 'Tx TAG' the same as 'Trunking'?

I'm wondering if 'Tx TAG' checked means 'pass all traffic tagged, and tag untagged traffic with VID'.

Tx commonly stands for 'transmit' or 'send'.

I'm wondering if 'Tx TAG' checked means 'pass all traffic tagged, and tag untagged traffic with VID'.

The PORT MAPPING SETTINGS section of the GUI obviously only allows to specify exactly one VID per PortX. VLAN-Trunking means to define at least two or more VIDs per PortX where any Ethernet frame that enters or leaves the port has to be tagged with a VID with the exception of exactly one VLAN (the 'native' VLAN), whose frames may be sent and received untagged (and which are internally tagged with the native VID). As a consequence your DSL-2770L does not support VLAN-Trunking (apart from the special case that you may consider a port with a single configured VID, that sends and receives tagged frames, as a VLAN-Trunk that consists of a single VLAN).

Tx Tag if checked means: Egress frames are tagged with the VID configured for that port and ingress frames are only accepted if they are also tagged with the VID configured for that port. You can consider this port as a VLAN-Trunk that consists of a single VLAN.

Tx Tag if unchecked means: The configured VID is only used internally: Ingress frames are only accepted if they are untagged (and after ingress they are only internally tagged with the VID configured for the ingress port) and egress frames are sent untagged (the internally used VID gets removed on egress). The corresponding port is commonly named an 'access port'.

EDIT: Maybe the DSL-2770L supports a special feature that any port configured for a VID > 1 with Tx Tag checked can be considered as a VLAN-Trunk consisting of two VLANs, where the default VLAN 1 is implicitely and unchangeably taken as the second and native VLAN of that VLAN-Trunk. If so your scenario might work if you configure port 3 for use of VLAN 1003 with Tx Tag checked.

Trunking will send any tagged frames, and the untagged native frame. So if this 'Tx TAG' is the same concept, then it could also mean 'pass all tagged traffic and native untagged' perhaps?

Will try it when I'm back near the device and report back.

Yes, this is in your words what I have said in the 'EDIT' part of my last post.

[FurryNutz]

Any status on this?

[mriksman]

I will update this post once I finish my shift in Egypt, fly back to Australia after being absent for 8 months, drink, recover from hangover, and attempt to set this device up with VLAN tagging.

Will update in about a month.

Good Luck.
