Terminal servers and ethernet bridges

[MARDEL%VMSAC.BITNET at cunyvm.cuny.edu]

we are looking for a terminal server , connected to our ETHERNET LAN ,
allowing connections between asynchronous terminals and either TCP-IP or
VAX hosts .

We are also looking for a filtering bridge to connect two ethernet
networks .We want it to be able to filter frames by protocols (XNS ,
TCP-IP or XNS ).

If you have any experiences of such devices , would you give me some
references about them?

Thanks in advance .

Would the manufacturers give the adress of their distributors in FRANCE?
