GPRS connection established, but no ping possible

I realised a GPRS-Connection with S45 handy. The log
seems to be okay, but ping is possible. Somebody here
who could give me a pointer?

That's what I've done:

/usr/sbin/pppd /dev/ttyS0 115200 connect 'chat -v "" ATH OK
AT+CGQREQ=1,2,4,3,9,31 OK
AT+CGDCONT=1,"IP","INTERNET.EPLUS.DE","",0,0 OK "ATD *99***1#"
CONNECT' noauth defaultroute nocrtscts noipdefault local
ipcp-accept-local novj novjccomp nobsdcomp noccp nodeflate
user eplus name eplus debug

/etc/pap/chap-secrets:
eplus * "gprs"


The output after typing: /usr/sbin/pppd /dev/ttyS0 115200 ... (see above)

I always get a IP but not ping to 192.168.254.254 possible!

Why?

Looks like the problem, anyway did you try "GPRS Easy Connect For
Linux", it's likely your provider and phone are already
preconfigured.

Good luck

GPRS seems *NOT* to allow ping at all!!!! I've never heard of so far!
Neither ping to IP of ppp-host possible nor to DNS-Server!

It's working: http, ftp, ...

My second fault was to leave the default route to my normal
DSL-gateway untouched! I thought that a second defaultroute
hides the first default route!? Now I know: I have to
delete the second defaultroute and the GPRS-connection works!

This is buggy:
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.254.254 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0

0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0

That's right: (no eth0-default)
