I have a dlink dir855 router that has been used uptonow with an optical fibre isp.  I have ditched the isp due to cost and gone for a adsl service. the isp provided a router which was a cheap one so i purchased the dlink dsl320b.

I have set it up to a fashion and it works as i am here now. Its in bridged mode with dhcp off. the router is now set to ppoe and has the connection settings in it.

So far so good.

I am not sure about the network address range. I had it set to -

the modem is set to

do i now need to change that address in the modem settings to 192.168.0.xx  or will it be ok on

If DHCP is not distributing any addresses it shouldn't matter.

????? If it has PPPoE then you get a public address when connected, no?
Then that means you're using NAT on the router, no?

I tried to look up the new device's sheet but it's being very slow .....

I've attached a simple model / diagram of a router.
Anyway, if your router is providing NAT, whether from public or private address space,you don't want the same subnet on both sides.
And, the "controls box" in the simple diagram can have an IP address assigned that's not in the LAN subnet.   BUT, if you do that then you can't reach the control panel unless the PC involved has an IP address on the same subnet.  This is a pain.  So, it's best to make the access IP address one that's in your LAN subnet.

I hope this is what you were asking.
