bypass local addresses and auto detect TS gateway

[Guest Tom Decaluwé]

Hi,

 

On the MSTSC client TS gateway tab you now have the option "bypass TS

gateway server for local addresses"

 

My question is, what does the client concider to be local? when does it

decide yes i need to use the TS gateway or no i don't i can directly connect?

 

1) does it look at the local NIC subnet

2) does it look at AD sites and services

3) does it do some sort of connection test

4)....

 

what determins the local yes or no answer?

 

As a second question i see you can select auto detection for TS gateway, but

how does this work?

 

1) does it broadcast for a TS gateway

2) does it query AD for TS gateway servers

3) does it look at specific DNS records

4)...

 

Any info is much apreaciated,

local = on the local network

From:

 

Configuring the TS Gateway Core Scenario

http://technet.microsoft.com/en-

us/library/cc754252.aspx#BKMK_ConfigureRDCSettings_TSGateway

 

Bypass TS Gateway server for local addresses. This option is

selected by default.

If you want the Terminal Services client to automatically detect

when TS Gateway is required, select this check box. If you use a

mobile computer, selecting this option will optimize client

connectivity performance and minimize latency because TS Gateway

will only be used when it is required. If your computer is always

connected to the local area network (LAN) or if it is hosted inside

the internal network firewall, TS Gateway will not be used. If you

are outside the internal network and connecting to the internal

network over the Internet, TS Gateway will be used.

If you are in a LAN, but want to test connectivity through a TS

Gateway server or TS Gateway server farm, clear this check box.

Otherwise, the client will not connect through the TS Gateway

server or TS Gateway server farm in this case.

From the same TechNet article:

 

Automatically detect TS Gateway server settings (default).

If you select this option, the Terminal Services client attempts to

use Group Policy settings that determine the behavior of client

connections to TS Gateway servers or TS Gateway server farms, if

these settings have been configured and enabled. For more

information, see the "Using Group Policy to Manage Client

Connections Through TS Gateway" topic in the TS Gateway Help.

Re: bypass local addresses and auto detect TS gateway

 

Hi,

 

We?re also testing Windows Terminal Services 2008, and it seems like the

option "bypass TS gateway server for local addresses" is not working as

it should.

If we test a connection with TS WebAccess across a TS Gateway with the

option enabled, the client is trying to connect the server (farm)

directly and after 1,5 minutes it is trying the gateway.

If we disable the option, the client immediately uses the Gateway and

the response time is ok.

We test the connection from a Home-Office, which is not integrated in

our network infrastructure. The internet connection is based on another

provider. So in my understanding, there should be no reason, why the

client is trying to connect the server (farm) directly.

 

Best greetings
