Networking issues on VRTX with PowerEdge M630

We ran into an issue while configuring the network for the first time on our VRTX server.

 

Our setup is a VRTX Rack Server with 2 PowerEdge M630 Blades running Microsoft Windows Server 2016 Standard. The switch is R1-2401 VRTX 1Gb Switch.
Firmware versions for these are:

• CMC: 3.10
• iDRAC 8: 2.50.50.50
• Blade BIOS: 2.8.0
• Host OS: Microsoft Windows Server 2016 Standard
• R1-2401 VRTX 1Gb Switch: 2.0.0.69
• NIC: BRCM 10GbE 2P 57810s bNDC - Family Firmware Version 14.02.12 - Family Driver Version 7.13.104.0

 

We have 2 network connections set up like this:

 

 

gi0/1 is a public subnet with x.x.x.32/28, with gateway x.x.x.33

oob is the management connection with only 1 IP addr like y.y.204.23 / 24 with gateway y.y.204.1. This is the address assigned to the CMC interface.

For the 2 iDRACs we have assigned 2 static ips from the subnet: x.x.x.34 and x.x.x.35 and they work fine.
No VLANs are configured.

 

The problem is within the Windows Server Host OS. When setting up IPv4 settings in windows, we are trying to use remaining addresses from the subnet: first tried x.x.x.36.

But there is no connectivity for the Host OS. Both blades have this same issue.
Ping to the gw address is not working.
ARP resolution does not seem to work - ARP table has an invalid entry for the gateway.

 

We were trying to achieve the most basic setup for our sever, but ran into this.. 
The server is re-located into a shared DataCenter, so we I don`t have additional details about the 2 networks connected to the server.

 

Any input is greatly appreciated.

 

Thank you,
