IRTCPortManager::UpdateRemoteAddress (Windows Embedded CE 6.0)
1/6/2010
This method informs the application that the remote address has been updated. Some NATs associate each port mapping with a particular remote address and will reject traffic from remote addresses other than the associated one. This method allows the application to update the remote address associated with a particular mapping on the NAT.
Syntax
HRESULT UpdateRemoteAddress(
BSTR bstrRemoteAddress,
BSTR bstrInternalLocalAddress,
long lInternalLocalPort,
BSTR bstrExternalLocalAddress,

Parameters
- bstrRemoteAddress
[in] The IP address of the remote endpoint for which the NAT mapping might be associated. Currently this parameter will contain an IPv4 dotted address. However, in the future an IPv6 address may also be entered in this parameter. The application must not assume this will be an IPv4 address.
