Is it possible to configure an ISA box with the following hardware. I have a ISDN modem for the uplink to the ISP and a Telemann SM200DTP for the downlink and of course an ethernet card for the LAN. Without ISA installed it connects fine and get a decent DL. However when ISA is running it does not work with the SM200DTP, only totally via the modem. I suspect that ISA is expecting the DL from the modem because of the low level nature of the program. If anyione out there has a slimilar configuration working please let me know. Thanks Shaun
