Hi. I have a problem with IJPPP and the tunnel drivers. What happens is that the connection seems to die when transmitting a lot of data. I can receive lots of data with no problem, but when I try and ftp out, it just dies on me. After it dies, I don't even get ping response from the other end. I've traced things a little, and packets go out OK, and packets come back through the modem OK, the ppp process receives them and writes them to the tunnel, but then they get lost. Any idea what is going on? Please help, this is very frustrating. System Details: FreeBSD 2.0.5-RELEASE 486 100MHz, 16M RAM, Adaptec SCSI, 16550 serial board, Microcom DeskPorte modem. My ISP is running Morning-Star PPP under Solaris if that helps. Mind you I've tried this against a different provider with the same results. The exact same hardware worked just fine with the same provider under Linux. Would any other info be useful?
