I want to setup the LANs so that they are on seperate networks,
According to the user manual you should be able to configure both LANs when network cables are connected to it.
I have connected two different networks to the LANs (2 green lights are on the network port) but i can not configure LAN 2 via the DNS 345 configuration UI
Any hints?
-
The manual describes link aggregation, which I believe requires an external managed switch to use, but I don't recall seeing any language about using both NICs to establish concurrent connections to two separate LANs. Would you please post what you read (and where)? ??? :-\

I think i figured it out
There are two Hardware versions, A1 & A2
The instruction manual for A1 ftp://files.dlink.com.au/products/DNS-345/REV_A/Manuals/DNS-345_A1_Manual_v1.00.pdf talks about configuring both LAN 1 and LAN 2
The instruction manual for A2 ftp://files.dlink.com.au/products/DNS-345/REV_A/Manuals/DNS-345_A2_Manual_v1.10%28WW%29.pdf talks about link aggregation
I have the A2 version, so i'm out of luck

My DNS-345s are hardware revision A2 as well. My gut tells me that even rev A1 does not support configuring the DNS-345 to work on two concurrent LANs, as that would not be a feature that I can see them removing for Rev 2, despite what the manual indicates.
Can you please post what the A1 manual says (and where you downloaded the manual from, with link). I'm curious myself as this is a feature I would use in a heartbeat if I knew it existed!

See page 52, ftp://files.dlink.com.au/products/DNS-345/REV_A/Manuals/DNS-345_A1_Manual_v1.00.pdf
There is definitely two LAN configurations for A1 hardware revision
I'm talking to D-Link support about this, will let you know what they say.

That's actually page 48 of the manual. The page appears as "52" only if you're viewing via web browser.
I'm not convinced those settings clearly imply two concurrent LAN connections. See manual pages 165 and 168 (downloading the PDF and viewing through Acrobat). In the A1 hardware Network Management section there's an option under LAN Setup > LAN Settings > Default Gateway to select either LAN 1 or LAN 2 as the Default Gateway, "For the Default Gateway, select either LAN 1 or LAN 2. The default gateway is your primary LAN port for accessing data on your network." These settings (and text) imply that you can use either LAN 1 or LAN 2, but not both. The Link Aggregation, I believe, is the only functionality that can leverage both LANs. I'm presuming that the "Default Gateway" section in the A2 hardware was removed to avoid confusion and all LAN 1 and LAN 2 references were rolled-up under the Link Aggregation configuration for the sake of simplification. :-\
As much as I'd like to be wrong, this is how I'm reading things. I hope you prove otherwise. ;)

Having done a few tests here with our DNS-345 it appears that you can NOT have separate lan ports. Yes, you can combine them or use a single port.
If you connect them both to a managed switch and set a default gateway you can get the second port to take over if the default port has problems.
There is absolutely no way that they can be connected to separate subnets and work. That requires much more sophistication on the main board and usually requires special a setup even on a server with dedicated lan cards.
So the answer to cexpo's question is no, you can't connect to two subnets.

Ivan - thanks, I presumed as much, but thanks for the validation.

Be aware that if you are unfortunate enough to enable link aggregation, it can't be undone.
I found that out the hard way when I changed some network hardware and wanted to revert back to separate NICs.
Another "feature" of the DNS-345. :o

The firmware settings don't stick?
-
No. Once link aggregation is chosen, you cannot separate the NICs. There is no provision for "undoing" the aggregation of the NICs.
I did it and then changed network hardware, and found that now I'm stuck with both NICs aggregated. Downgrading firmware, resetting to factory defaults, nothing.
I posted something about this on this forum some time ago, and nothing was ever resolved.
