           Summary: PPP can only route to subnet if using a null modem
           Product: eCos
           Version: 3.0
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: major
          Priority: low
         Component: TCP/IP
        AssignedTo: unassigned@bugs.ecos.sourceware.org
        ReportedBy: kenkyee@excite.com
                CC: ecos-bugs@ecos.sourceware.org
             Class: Advice Request


If you bring up pppd on a Linux machine connected to a null modem to eCos, eCos
only seems to know how to route to the local subnet.

pppd was started as follows (the local subnet is 192.168.50.x):

pppd noauth nodetach nocrtscts nobsdcomp nodeflate ms-dns 66.189.0.100 local
lock persist debug dump logfd 1 proxyarp defaultroute
192.168.50.251:192.168.50.252 /dev/ttyS0 9600

You can't ping a remote server (e.g., Google's DNS server at 8.8.8.8).  Packets
seem to go out and come back onto the interface (tested w/ serial port
breakout) and eCos doesn't see them.

Might be related to this bug setting neg_accm in the PPP options made no
difference: http://sources.redhat.com/ml/ecos-discuss/2004-12/msg00041.html
