multiple internet connections for incoming rdp sessions

Hi all,

I have a 2003 server running terminal services in application mode.

This server has two NICs and two internet connections via adsl.

I can only connect to the server remotely on the connection using the
default gateway.

nw1 - server ip 192.168.0.11 adsl router at 192.168.0.1 (wan is 203.x.x.x)
nw2 - server ip 10.1.1.11 adsl router at 10.1.1.1 (wan is 204.x.x.x)

if the default gateway on the server is set to 192.168.0.1 then remote
desktop will connect to the server via 203.x.x.x but will not connect to the
server via 204.x.x.x

The reverse is also true, setting the default gateway on the server to
10.1.1.1 will only allow connections form 204.x.x.x

What do I need to do to allow connections from both external ip addresses
concurrently?

Thanks in advance.

Regards,

Ross Fraser

Go to Terminal Services Configuration and create an RDP connection for each
of the network cards. This is all you do from the TS side, all the rest is
standard network configuration.

Re: multiple internet connections for incoming rdp sessions

Thanks for your reply Benny.

I have already set up two RDP connections on the server, one for each card.

If I connect a workstation on either lan segment I can connect to the TS
without a problem. The problem only occurs when I connect to the server
through a router via the internet.

As I said earlier both incoming connections will work IF the default gateway
on the server points to the router I connect to from the outside. Connecting
through the other always fails.

I hope that gives you enough information.

Thanks again

Ross.

Re: multiple internet connections for incoming rdp sessions

Hi Ross,

For this I recommend you use a bandwidth aggregation
device. The device will connect directly to your two DSL
modems and your internal network and manage the traffic
between the two. You need to choose one that has the
ability to do what you need--making sure that connections
that come in from one DSL will go back out the same way.
Your TS will only need one NIC.

I recommend that you contact each company and explain
to them *exactly* your needs regarding *incoming* connections
that must remain "sticky" to a particular WAN link. Some
of the products available are focused more on the other
side--load balancing internal users connecting to web sites
over multiple Internet connections.

There are many available so you will need to do some
research. Some manufacturers have evaluation models so
that you can try out the device and send it back if you are
unhappy. Other solutions are available that are software
based and will require a PC with multiple NICs for them to
run on. There are inexpensive ones based on Linux if you
are technically savy and willing to do the configuration
yourself.

For example, look at this manufacturer's Vector Routing
description as well as the diagram at the bottom of the page:
