The answer depends on what exactly you have. How is the 3090 connected to the token ring (that is, if it is connected already). Assuming you already have basic TCP/IP connection from the token ring to the 3090 (via 3172?): if you have an Internet router already (like the Cisco AGS), you might add a token ring interface to that router and get IP routing between the two LANs. For TCP/IP, this would serve your purpose. Also, I believe an RS/6000 station, properly configured, can sit on both LANs and perform IP routing between them. Obviously the basic price of an RS/6000 is higher than that of an 8209; but if you already have one... Doron
