[ofa-general] ***SPAM*** WinOF - MT21308 - win2k3 problem in MS network

I have problem with SFS Topspin 90 switch in MS network.

1. LAN Topology: remote workstation (win2k3 fresh installation, ethernet
NIC, IP 192.168.1.2) <-> ethernet router/DHCP (Zywall 5, IP 192.168.1.1))
<-> Topspin 90/6p eth. gateway <-> HCA/server/win2k3 - fresh installation

2. Like HCAs I have tried PCI-E Voltaire 410EX-D and Mellanox PCI-X MT23108.
In the first case with IBoIP from Voltaire, in second from Mellanox and also
with WinOF. Both firmwares were updated.

3. All LEDs (Topspin, HCAs) signalize, that all devices are in correct
status.

4. Topspin was configured by the most simple setting - as "no VAN + default
PKEY". Set correct suffix (192.168.1.0), length (24), choosen correct ports
for bridge mode (2/1 + 2/1(gw)), enabled broadcast forwarding. Other
default.

5. PROBLEM description:

5.1 HCA 410EX-D & IPoIB from Voltaire:
5.1.1 pinging (from HCA based server) to 192.168.1.2 works fine
5.1.2 iperf from both sides works excellent
5.1.3 remote desktops from both sides works
5.1.4 ping (from HCA based server) to any WAN IP does not work
5.1.5 ping (from HCA based server) to WAN webserver by domain name does not
work (IP is not viewed)
5.1.6 no webbrowser (IE6) connection to any WAN web server (nor by IP of
webserver!)
5.1.7 no possibility to browse computers in local MS workgroup (only seen
server with HCA). By IPs of workstation there is possible to browse
correctly.

5.2 Mellanox (PCI-X) MT21308 and IPoIB from WinOF:
5.2.1 DHCP can not afford IP - no available MAC for HCA ports (-> no network
communication)
5.2.2 IP/subnet mask/def. gateway assigned manually -> no net communication

Any idea?

Thanks, Simon
