Hello Brian: Before I attempt any other changes I have decided to send along the ppp.config files for both the ppp server machine mail and the ppp client machine tpe. They are included at the end of this message. The connection between them is a dedicated line with special modems; this accounts for there being no modem config information in the config files. PPP does not use chap, pap or mgetty on the server serial ports (mgetty was problem prone). The client machine tpe itself serves as a gateway for windows machines and other freebsd machines that form a local lan at the remote site. They read mail via pop from the ppp server machine mail; they must be able to reach mail directly. To recap the machines connected to the client ppp machine tpe (and tpe itself) can ping past mail but that is all. Telnet functions between mail <---> tpe but not ftp or rlogin. Thanks much for your help. Daniel C.
