VAXStation and TCP/IP

For dome timre I'm trying to connecyt my VAXStation 3100 to PC runing Linux via TCP/IP and thin wire ethernet. I got TCP/IP services (origanal Digital's tcp/ip for OpenVMS 7.2) running and passing all internal test. However I can't get connection. I suppose the problem is in network interface. Interface passes boot time test and i can get it's hardware addres, so it is OK I hope. The swith on the back of unit is set properly - the green LED is lit on side of BNC connector. Using '$ SHOW DEV' command I can see one network interface 'ESA0:' which is online and labelaed as 'template devece' (whatever it means...). After starting up TCP/IP I get two other interfaces 'ESA3:' and 'ESA5:' owned by processes related to TCP/IP services. Does anybody know what I've to do to get my network up ? Maciek
