Advice on network setup
Advice on network setup
Not sure this is the right place for this but I felt it was the most suitable given the nature of my query.
I have a small network setup which contains 3, or maybe 4, network devices which 'manage' the comms.
Recently, the ADSL was upgraded and a new BT (this is in the UK) modem was supplied - VDSL modem??. Previously, our ADSL was managed by a Draytek 2820 modem/router. I now need to connect to the new BT modem with the Draytek using the WAN2 port configured as a PPPoE type of connection. That's all fine and works well.
The Draytek has 4 LAN ports on it and I have a server (Ubuntu) on it and a Apple Airport Express plugged into it. The Draytek acts as a DHCP server and assigns IP addresses in the 192.168.0.10-50 range. The Airport assigns IP addresses from 192.168.0.51 up to 50 addresses.
There is also a DELL PowerConnect 2724 switch which is connected to the Draytek 2820. I have not configured this switch at all and I think therein lies my problem, which is this:
If I have a client machine plugged into the Draytek, I get internet access and local LAN access (I can browse the web and also see the server on 192.168.0.10). If I connect that same machine into the DELL switch, I get internet access but I cannot see the local network (I cannot see the local server). If I connect over wi-fi, I get internet access and local network access (I can see the server).
The issue is I don't want client desktops on wi-fi as I have the offices cabled (back the DELL switch). I want to offer wi-fi for iPad's etc.
My thoughts are that I need to do something with the DELL switch as when I connect a client directly into the Draytek, everything is fine, but when I connect to the DELL switch, I do not get local network access. I think it works over the wi-fi as the Airport is directly connected to the Draytek.
As I say, I have not looked at the switch yet to configure it (this was a previous network I inherited so its not a switch out of the box).
I have read that the switch can be in managed or unmanaged mode and I'm not sure what it is setup as right now (I know I can tell from the managed light on the back but I'm not near it right now).
But I suppose I simply want the switch to act dumb and pass on IP addresses as assigned by the Draytek??
Any help appreciated.
