Question: Sticky Static IP (PPPoE) + Port Forwarding

Hello,

I'm helping my client with router setup.
He wants to access his computer in the office from outside.
To have static IPs, he upgraded his DSL service.
I went to him for router setup (D-Link EBR-2310).
However, I found out that it's not true static IP but sticky static
IP.
It uses PPPoE (with username and password) instead of static IP.

The IPs are like this (I'm hiding the real ip):

IP Address: x.x.x.176
Default Gateway: x.x.x.182
Subnet mask: 255.255.255.248
Useable IPs: x.x.x.177~181 (5 useable IPs)

When the router is connected, it has x.x.x.182.

Now I have 2 options:
1. Assign private IPs to computers: router - 192.168.0.1, computers -
192.168.0.xxx
2. Assign public IPs to computers: router - x.x.x.176, computers -
x.x.x.177~181 (Default Gateway: x.x.x.176)

Either way, the Internet connection is fine.

The problem is that I can't make external traffic access to an
internal computer.
For private IP, I set up port forwarding for port 3389.
But it didn't work.
For public IP, I should be able to directly access the computer and
for some reason it didn't work.

Is there any limitation for sticky static ips?
I called AT&T and asked about it and they said that if I set up NAT on
the router it should work.
What's the difference between normal routing and NAT?

Thanks.

If you need to ask questions here your client should get a different
network consultant.

You may be right...:-)
I admit that I am not an expert in that area.
I'm a programmer.
And I am helping my client with this free of charge.

Do you have any idea about how to solve my problem?
If so, please help me.

Hi.

The office network probably has a firewall (it should!) that prevents this
kind of sneaking into it!

You should set-up the home LAN IAW the EBR-2310 manual paying particular
attention to page 11.

Thank you for the input.
The router is the only firewall and I opened it up already.
Any other idea?

Travis,

I found out that something is wrong.

IP Address: x.x.x.176
Default Gateway: x.x.x.182
Subnet mask: 255.255.255.248
Useable IPs: x.x.x.177~181 (5 useable IPs)

When I set the ip on the router, the external was x.x.x.182 and the
internal was x.x.x.176.
But they are in the same subnet (255.255.255.248).
So probably it shouldn't work.
How do I use all the public IPs?

I just figure out that it should be bridged not routed.
D-Link router doesn't support bridge mode.
Known compatible routers are listed at http://www.dslreports.com/faq/3759

Why don't you follow the directions in the router manual?


There are 5 WAN IP's from x.x.x.177 to 181

A router is used when there is only one (1) public IP and you want to
share it with multiple computers.

If your client wants to run a server on his network he probably will
need business class DSL and a static IP.

In the router:
The Default Gateway is 192.168.0.1
The Subnet Mask is 255.255.255.0

If you want the 5 public IP's going to 5 computers all you need is a
switch. Then set each computer to use static IP and assign a different
IP to each computer.

(I Hate bottom posting)
If the router has ppoe settings, then first connect the modem direcctly to
the computer... access the web page (what ever it says on bottom of modem
.... also note the access code) put the modem in bridge mode and let the
router do the PPoE

PS a tunnel setup also works great
