1. pppd fails to receive IP-address

I just face the challenging task to connect my laptop via
infrared/mobile/gprs to internet.
By now all is working almost to the end, pppd gets an connection, but then
it reports that it didnt receive ip-adresses and uses the default-adress.
This is the wrong adress, cause I cant even ping the given remote-adress -
not to talk about any other address. Ping just doesnt give any respond.
Routes are set ok and pppd is running until its killed.

# tcpdump -i ppp0
tcpdump: listening on ppp0
01:33:26.460128 10.100.0.1 > 195.58.176.137: icmp: echo request (DF)
01:33:27.460098 10.100.0.1 > 195.58.176.137: icmp: echo request (DF)
01:33:28.460132 10.100.0.1 > 195.58.176.137: icmp: echo request (DF)
01:33:29.460105 10.100.0.1 > 195.58.176.137: icmp: echo request (DF)
....

syslog looks like this: (the strange dialout-number is for the
gprs-connection)

What does this tell me ?
Is this actually a proove that there is at least a pppd-connection, cause a
local address was received ?
Or doesnt it mean anything ?

Can there be any problem with the options in my pppd-call like wrong
compressions or something ?

pppd $PORT connect "chat -v -f $CHATFILE" $SPEED modem crtscts \
defaultroute  user $USER remotename $REMOTE

any advice would be appretiated, cause I'feel a bit in the dark here ...

thnx,
peter
