bought one of these, so far not impressed.

not sure if its related to my network.  i have 2 netgears.  one acts as a modem dg632, the router is a rangemax wp824.  all wired/wireless pc's ipads etc work fine on the web.

how can i config this thing to get online.  the av scanner isnt updating.  the gateway setting on the nas is the router not modem, which is the same as all other pc's....

ideas?

When you say you want the DS411j to get online, do you mean you want to be able to access it from the internet? If so, chapter 5 of the user guide explains how to set this up either with their wizard, or manually if you want customise things like port ranges.

If not, what are you trying to do?

How does the AV scanner fit into the picture?

yes access it from the internet.  
But also the device cannot route though my router to the modem onto the web.  
Testing the AV update and other services says internet fails.

Its not got these 2x netgear devices on the HCL so i suspect synology wont want to help.....

All other devices, wired and wireless work fine, so i suspect its a limitation of the NAS...

I'm not understanding why the Synology unit won't work with just about any router. The HCL lists a large number of routers, and it seems that these are just the ones that will work with Synology's EZ-Internet utility. Synology provides manual setup instructions here:

http://www.synology.com/tutorials/how_to_access_nas_with_internet.php?lang=enu

which gives detailed information on how to set up a router to allow internet access to your NAS unit.
It seems that the WPN824 does not support UPnP, which is what the EZ-Internet wizard is expecting, so you will have to configure it manually anyway.
Is the router running the latest version of the firmware? Be careful here, if you are going to update; there are three different versions of the WPN824, and each has its own firmware. Using the wrong firmware version can brick your device!

The modem is probably not part of the problem, as it is only that - a modem.

Something I forgot to ask - what version of DSM is the Synology running?

The latest version can be found here:

http://www.synology.com/support/download.php?lang=enu&b=4%20bays&m=DS411j

and is very likely to be newer than the one that came with your unit, as it's dated 8th March this year.

the dg632 is actually configured in router mode.  

i have tried to allow port 80 be open and configure a firewall rule for the wp824 but it doesnt work as the ip ranges are different.

the wp824 has upnp setup and rules configured....

running dsm4.0

I think that this is the cause of the problem - if both the modem and the router are doing NAT then the incoming traffic is going present a private IP address to the WAN interface of your DG632, which will promptly discard it.

I suggest that you configure your DG632 to operate in bridge mode, and leave the routing to the router! Log in to your device, and when the Basic Settings screen appears, click on the down arrow on Device Mode and choose the Modem setting. Netgear provides more information and screenshots here:

ftp://downloads.netgear.com/files/dg632_manual.pdf

I can't recall if the DG632 will still do the authentication in bridge mode, or whether the WPN824 has to do it, as it's some time since I worked with either of these devices.

However, I'm sure that removing the double NAT setup you have at the moment and replacing it with the above configuration will resolve your problem.

unfortunately it only come ins modem or router mode.  if modem then its 1x ethernet connection to a switch, i.e. the wireless router will not work.

i'll have a read...

Can you provide a sketch of how the various components of your network are connected together?

I get from your last post that your layout is modem -> switch -> router. If so, then it should look like this: modem -> router -> switch.

No, Modem - Router (in built switch).

OK. The DG632 in router mode is effectively a single-port switch. If you configure it as a modem so that it simply forwards your public IP to the WAN interface of your WPN824, then the latter will function as a router, wireless access point, and switch all in one, which is what it's designed to do.

You will not be able to access your NAS from the internet until or unless you disable the NAT on the DG632 and configure the router to do the job. The WPN824 comes with a CD that contains a wizard for configuring the device for you, thought its instructions have to be followed to the letter...

What kind of internet connection do you have? Do you have to authenticate to your ISP's network to get online?

Can you get an internet connection by connecting a computer's NIC directly to the DG632 when the latter is in modem mode? You would enter username and password credentials via the PPP dial-up interface, effectively "dialling in" to your ISP. If you then did an ipconfig /all, the IP information would be the public IP address, subnet mask, gateway,and DNS server addresses provided by your ISP; if you just get zeros, your ISP is using a different protocol. If it worked, this would also indicate that your ISP is using DHCP to assign addresses to its customers.

Assuming that you are able to connect in this way, you would then connect your DG632 to the internet port of your WPN824 and set it up to receive all the ISP's IP address information from the ISP's DHCP server, and to supply the user credentials if the DG632 didn't or couldn't. The WPN824 would then do the NAT to the private IP address range 192.168.1.x (the default) and its own LAN DHCP server would provide addresses in that range to DHCP clients connected to any of the four switch ports on the back of the unit. Similarly, the unit would also manage the WLAN side of things, using the same address range.

Essentially, this is a network problem, not a storage one, and you may want to consider moving the question to the network area of EE. It's very likely that others will be able to offer more helpful and concise guidance than I've been able to so far.
