Hallo,

I noticed that after installing the OFED driver on our Windows 2008 Server, the route table has been changed, the IB card interface gets the highest priority for internet connection, which causes some connection problems. This issue exists in all the OFED snapshots and v2.2.1. Does anyone know if it's caused by the driver or anything else? How can I solve this problem? Thanks a lot.

Here is the "route print" output on our machine (192.168.2.125 is the IB interface IP):

Network Destination        Netmask          Gateway       Interface  Metric
