Just ordered the 5500 and pretty pumped had the 4500 for a while then the wireless bands died on it and got a basic d-link one to replace.  Now back to the new DGL.

For example on the network settings page under setup can you do this?

router ip: 192.168.10.1
subnet: 255.255.255.0

DHCP: enabled
DHCP address range: 192.168.10.244 to 192.168.10.254

and then use the reservation list to use the other ip addresses 192.168.10.2 to 192.168.10.243?

OR

DHCP address range: 192.168.11.244 to 192.168.11.254
to separate the DHCP devices from the reserved devices?

I am mainly looking to separate the DHCP devices from the reservation list

Follow up question, I am going to be using a synology server on this router which could do DHCP for me if it is  not possible to do this type of configuration on the 5500 and I could disable it on the router side

If you're using a class C 255.255.255.0 subnet you are limited to 192.168.10.1 - 192.168.10.254
If you are needing more hosts i'd suggest dropping down to a class B subnet 255.255.254.0 which will give you 191.168.10.1 - 191.168.11.254.

It all depends on how many hosts you need.. if 254 is plenty i'd stick with a class C and seperate the DHCP pool from the reservation range of IPs.

You can use the following page to figure it out:

Thanks I think I am going to just separate the DHCP pool from the reservation list IPs, easier to setup and manage

[FurryNutz]

Just curious as why you need this more complex DHCP setup? Using reserved IP addressing is preferred accept for the using of wireless bridges maybe.

[junkie-xl]

NIS,

Both of my recommendations require seperating the DHCP pool from the reservation IP list, but your second example wouldn't work with a class C subnet, it would require a class B.

[NIS4]

I under stand your point with class b and c, I thought about doing b but unnecessary, I do not have that many devices.

Furry - The reason I want to do this more complicated setup is that only my devices are on the reserved list and when a friend comes over and needs to use the net there is a limited number of IP address that can be given out.  I was trying to separate the DHCP ip address from the reserved ones so that they cannot communicate with each other.  junkie's point on jumping up to b class is the only way with would work with two different subnets so that my devices and my "guest" devices could not communicate with each other, at least from what I think I know about subnets.

Just a small addition of security even though it really is not security like a firewall or something else.

From using the website that junkie posted does this make sense?

Class C network
Subnet Mask: 255.255.255.128 (maximum 2 subnets)

Subnet #1
192.168.1.1 to 192.1681.126
subnet id 192.168.1.0
broadcast address 192.168.1.127

Subnet #2
192.168.1.128 to 192.168.1.254
subnet id 192.168.1.128
broadcast address 192.168.1.255

If the router is located at 192.168.1.1 would subnet 2 be able to communicate to the router? if not just going to stick with the separated lists.

I presume if your using the Basic D-Link model router, you could try this:
How to extend network without AP Mode using a Router

NIS, the problem you'll run into with that setup is the Router is only capable of being in one of the subnets, not both.  A class B subnet won't work in this case either.     What you need is a router with a guest network feature - that keeps guests on a seperate network.   Or a second router double nat setup, your guests can get online through the second router that is using the first router as a gateway.

router1 192.168.10.1
router2 10.10.10.1 
router1 plugs into the Internet port on router2

Gotcha, answers all of my questions, thanks for the help

[NIS4]

So after getting the 5500 today and testing around with it, it will not allow you to set DHCP reservation address outside of the DHCP address range, yes this makes sense but kind of annoying

using my synology server for DHCP as I cannot do what I want to on the 5500

otherwise good device came with 1.01 fw, great signal strength goes along way, liking what I got just need to get the DHCP the way I like it

[FurryNutz]

Most D-Link routers wont allow settings of IP addresses out side the DHCP IP Pool. You should be able to set up static IP addresses out side this range on the device however.

Glad it's working well for you. Keep us posted on your experiences.

Enjoy.
