Two IP addresses for WEC7 and DM3730

All,

We used to use two IP addresses in our CE6 system (one internal and one external). Now, we'd like to use the same with WEC7 (CE7) and with exactly the same settings the second IP address is ignored.

Our design is very similar to the EVM board - we use the SMSC adapter and we set two IP addresses this way:

 [HKEY_LOCAL_MACHINE\Comm\SMSC91181\Parms\TcpIp]
    "EnableDHCP"=dword:0
    "IpAddress"=multi_sz:"192.168.0.22","192.168.1.3"
    "Subnetmask"=multi_sz:"255.255.255.0","255.255.255.0"
    "DefaultGateway"="192.168.1.1"
    "UseZeroBroadcast"=dword:0

With exactly the same hardware, it doesn't work for CE7.

The "ipconfig /all" for CE6 shows both IP addresses, for CE7 only the first one is displayed (and used).

Please let me know if you have any thoughts on this.

Thank you!

Best regards,

Zack

    OK, I have a workaround.  The command AddIPAddress still adds the second IP address and we can call it on every system startup.

    Best regards,

    Hello,

    I found the code that is responsible for iterating through the multiple IP addresses specified in the registry for an adapter. Unfortunately, the WEC7 source code that is equivalent to this CE6 function is not available as shared source code so I am not able to compare and find out what was changed. Without access to this source from Microsoft, all I can advise you to do is to make sure you have all WEC7 updates. Beyond that, you will need to submit a support ticket to Microsoft.
