Multiple IP address in Colibri T30 WEC2013. Is it Possible?

In Windows7 from other company-board we used multiple IP addresses. But now I set two IPs and Two Subnetmasks in WEC2013 inside Colibri T30. Only the first IP-Address was ping-able. The second IP was ignored and is not effectively there.
Is setting multiple IP-Address is possible for Colibri T30 + WEC213 ?

I close this question as the same one is already placed here. Could please check the comment here: https://www.toradex.com/community/questions/2745/dual-or-mutiple-ip-address-in-t30-ethernet-adapter.html
