Windows 2003 - RAS

Hi,
I am running Windows 2003 standard edition on HP Proliant
ML350.
1. The Server is installed with D-link internal modem and
d-link external modem.
Routing and Remote access is configured.
I can dial to external modem from outside but i cannot
dial to internal modem.
The modem is working fine.

2. when server is installed with D-link and prolink
internal modem, i cannot dial in from outside for both the
modems.

Let me know how to resolve this issue.

Thanks,
Prashanth
