Re: Time Capsule configuration problem


Been struggling to set up my NetGear ADSL modem and TimeCapsule router.

I can get the NetGear configured to access my ADSL account if I plug my
MacBook in via ethernet.

I can get the TimeCapsule to allow me to mount volumes on other machines
locally via wireless connection but not access the internet for some
reason.

It seems to revolve around problems with the fixed IP address I need to
assign my MacBook (using DHCP gets me closer to internet access but not
quite there).

Is there a configure your set up for dummies guide available somewhere
online?

Also need to set up port forwarding to one machine on my network for web
hosting but I guess that is stage two of the problem.

It's a NetGear DM111P if that makes any difference. Very few parameters
to configure which concerns me somewhat.

In that case you should ignore the details in my earlier message. I'm
not familiar with the DM111P but I've just downloaded the manual...

The DM111P is a simple modem with a very basic router. It has a DHCP
server (which can be turned off) and no firewall.

It is unclear to me whether this modem supports NAT (Network Address
Translation). It looks like it doesn't, in which case it won't work at
all unless you are using one or more static IP addresses which have been
assigned to you by your ISP. (This is how my cable modem is configured,
but differs from how ADSL operates in New Zealand.)

Is that the "fixed IP address" you mention above?

Yes, I have a static IP address assigned by my ISP.

If so, a summary of the configuration you will need to set up is as
follows:

1. The Netgear modem's DHCP server should be turned off. The NetGear
mdoem should remain set to its default IP address (probably
192.168.0.1).

The only way to turn off the DHCP server on the Netgear is to use the
RFC1483 Bridged option rather than PPPoA/PPPoE. Using either of the
PPPoA/PPPoE address causes the DHCP buttons to be greyed out so it
cannot be turned off.

Although Demon requires PPPoA it *seems* to connect.

2. You need to configure the Time Capsule to use the fixed IP address,
subnet mask and gateway assigned by your ISP, and enter the addresses of
your ISP's DNS servers. (This is in the "Internet" area of Airport
Utility manual configuration.)

My previous router used this fixed IP address plus a default gateway
address (no idea what this is).

Is the default gateway address the address that I need to put in the
router address field? I had assumed that field should contain the
192.168.1.1 address.

3. The Time Capsule must be set to "Share a public IP address" (setting
near the bottom of the first tab in the Internet section), and its DHCP
and NAT features are then enabled. You should pick a private address
range such as 192.168.1.* to use for your local area nework. It should
be different from the address range used by the NetGear modem (i.e. not
192.168.0.*).

The Time Capsule's LAN address should be configured as 192.168.1.1, and
its DHCP server should be set to assign addresses in the range
192.168.1.2 through 192.168.1.99 (or higher as you see fit), with a
subnet mask of 255.255.255.0.

Whatever I do at this point I get "The router address you have entered
is not compatible with your WAN IP address".

No idea what this means or how to work around it.

4. All computers should be configured to use a DHCP server.

This should give you Internet access from the computers via the Time
Capsule.

Have not been able to connect to the internet as yet.

Stage 2:

To allow outside connections to a web server, you can enter port mapping
rules on the Time Capsule (and it can assign different external and
internal port numbers).

You will need a fixed IP address for the computer running a web server,
which can be handled by getting the Time Capsule to assign a fixed
address via DHCP, or by manually configuring the computer to a fixed
address outside the range of the DHCP server but still inside the range
of the network given the subnet mask (e.g. 192.168.1.100 if you used my
suggested settings above).
