serial GPRS modem + wvdial + fix APN + big headache

Hello all,
system: openSUSE 11.? server (no gui)

so to make long story short: I'm using wvdial to dial the GPRS modem the output seems to indicate ok

Code:

linux-fepu:~ # wvdial
--> WvDial: Internet dialer version 1.60
--> Initializing modem.
--> Sending: ATZ
ATZ
OK
--> Sending: AT
AT
OK
--> Sending: AT+CSQ
AT+CSQ
+CSQ: 15,0
OK
--> Sending: AT&D1&C1&S1
AT&D1&C1&S1
OK
--> Sending: AT+CGDCONT=1,"IP","fixvpn.gr.hu"
AT+CGDCONT=1,"IP","fixvpn.gr.hu"
OK
--> Sending: AT*ENAD=1,"GPRS 1","","",1,0,0
AT*ENAD=1,"GPRS 1","","",1,0,0
*ENAD: 1, 1
OK
--> Modem initialized.
--> Sending: ATD*99***1#
--> Waiting for carrier.
ATD*99***1#
CONNECT
--> Carrier detected.  Starting PPP immediately.
--> Starting pppd at Mon Nov 30 12:09:17 2009
--> Pid of pppd: 4682
--> Using interface ppp0
--> pppd: [18]¸[06][08]h¸[06][08]¸[06][08]¸[06][08]
--> pppd: [18]¸[06][08]h¸[06][08]¸[06][08]¸[06][08]
--> local  IP address 10.64.64.64
--> pppd: [18]¸[06][08]h¸[06][08]¸[06][08]¸[06][08]
--> remote IP address 10.112.112.112
--> pppd: [18]¸[06][08]h¸[06][08]¸[06][08]¸[06][08]

also ifconfig seem to indicate that ppp0 is up:

Code:

...
ppp0      Link encap:Point-to-Point Protocol
          inet addr:10.64.64.64  P-t-P:10.112.112.112  Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

there is an unplugged eth card on the machine.
the APN creates, using T-Mobil, a direct VPN access to company network.
but when I try to ping another computer in the network I get an "Host Unreachable" message...

any Ideas?

It seems like DNS problem.

Edit your /etc/resolv.conf,

Enter this DNS (OpenDNS)

Code:

nameserver 208.67.220.220
nameserver 208.67.222.222

Retry wvdial, retry ping.

Hmm, it doesn't help, it still doesn't ping, I also tried adding the ip given to the sim card by t-mobile.

is there something I need to kno w regarding that fix IP? any ideas?

Thanks a lot,
