I've been trying to connect to the Internet in DSL via a GPRS enabled mobile phone.

It looks like I'm connecting and it looks like I'm sending data out from the phone - the problem is that it looks like the data does not get back from the phone to my DSL machine.

I have the feeling I need some kind of ppp command to tie things up - does anybody have any ideas?

CONNECT
--> Carrier detected. Starting PPP immediately.
--> Starting pppd at Sat Jan 13 15:20:30 2007
--> pid of pppd: 1492
--> Using interface ppp0
--> pppd: =0
--> pppd: =0
--> local IP address 217.165.202.235
--> pppd: =0
--> remote IP 217.165.202.234
--> pppd: =0
--> primary DNS address 195.229.241.222
--> pppd: =0
--> secondary DNS address 213.42.20.20
--> pppd: =0

At this point I opened another terminal window and tried to ping various address - the only address I get is the remote IP address:

# ping 217.165.202.234
PING 217.165.202.234 (217.165.202.234): 56 data bytes

What is the output of the route command?
Who/What provides your gateway?

In the same fashion as dial-up using a "normal" modem, I was presuming that the ISP would provide the gateway - I can browse the Internet directly from the phone using GPRS

I'm still trying to make this work (irritatingly, GPRS over Bluetooth and irda works in W2K without any setup at all) and wondered if using wvdial on DSL might be the problem.

I looked at the ppp directories in DSL right after boot and found that etc/ppp is symlinked to /opt/ppp and thus the /peers subdirectory appears as /opt/ppp/peers.

Although the wvdial application is not present in DSL, there are two files in /opt/ppp/peers with wvdial in their name:

wvdial
------
noauth
name wvdial
usepeerdns

wvdial-pipe
-----------
noauth
name wvdial
plugin passwordfd.so
defaultroute
replacedefaultroute

Does anybody know of a reason for these two files to be present?

If I install the deb package for wvdial, it places files in etc/ppp and etc/ppp/peers and thus overwrites the symlink to /opt/ppp. Whilst this doesn't appear to be a problem for "dial-up classic" with wvdial, I'm wondering if this is the reason why GPRS dial-up apparently connects, data goes out but nothing appears to make it back to DSL?

Any suggestions would be welcome
