I followed the setup "after the book", nothing suspicious. "after the book" = the IP of the host itself is not on igb1 but on a different interface or on the bridge? Is there a firewall active on the box itself? Which one? What does wireshark / a traffic dump at the physical interface level tell compared to a traffic dump at the switch interface? Did you replace the cable / SFP / move to a different switch port as a test? I suggest to provide the output of ifconfig -a and netstat -rn (feel free to mangle the IPs, as long as the mangling is a consistent replacement and not a cut-off).
