unable connects to the ts gateway

[taki7878]

Hardware: 3 computers, 1 home use router

the 1st and 2nd computers have been added within same domain(test.com)

 

1st computer - dc.test.com (with AD and DNS) ip 192.168.1.1

2nd computer - ts.test.com (with tsGateway and ADCS) ip 192.168.1.2

 

3rd computer - client.outsider.com (different domain, with Win xp sp3) ip 192.168.2.1

 

router - ip 192.168.1.100

 

i want to use my 3rd computer to connect the tsGateway(ts.test.com) , and then, remote the ad server(dc.test.com).

i have stick the cables(form 3 computers) to the lan ports of the router(all the computers connected to the lan port), and i use the "remote desk" program from my 3th computer to remote the ad server through the tsGateway, it is failed, but i saw the event id 201 on the tsGateway....it is means, i have connected to the tsGateway.

But with the same setting, i stick the 3rd computer to the wan port(so, now, ad and gateway use lan port, client from the outside), i cant connect to the ts gateway, the tsGateway event table didnt show me any information (my computer cant find the ts gateway).

 

i have open the 80, 443, 3389 ports in the router, and forward then to the 192.168.1.2 already. also, i have tried the different gateway ip at the client side - 192.168.1.100, 192.168.1.2, 192.168.2.3....but not work!!

 

can someone here give some advice???????
