Hello,

I have the following situation i cannot figure out how to solve.
I need to have the foxboard to be reached from the internet using the 
GPRS link, simple as that. I have my foxboard flashed with dynamic IP 
and a connection with GPRS. I am now able to ping from inside 
foxboard to this outside IP, but still cannot reach this IP from 
internet. There must be something wrong with route i should set.

Here is what i did:

* started the foxboard with dynamic IP, now i got the internal IP 
from my router:
eth0      Link encap:Ethernet  HWaddr 00:40:8C:16:85:25  
          inet addr:192.168.254.4  Bcast:192.168.254.255  
Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:317 errors:0 dropped:0 overruns:0 frame:0
          TX packets:189 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:27794 (27.1 KiB)  TX bytes:20815 (20.3 KiB)
          Interrupt:17 DMA chan:1 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  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:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

here is the actual IP route:
Destination     Gateway         Genmask         Flags Metric Ref    
Use Iface
192.168.254.0   *               255.255.255.0   U     0      0

default         192.168.254.254 0.0.0.0         UG    0      0        
0 eth0


* started a GPRS link with PPP:
eth0      Link encap:Ethernet  HWaddr 00:40:8C:16:85:25  
          inet addr:192.168.254.4  Bcast:192.168.254.255

          inet addr:189.88.28.174  P-t-P:192.168.202.0

          collisions:0 txqueuelen:3 
          RX bytes:80 (80.0 B)  TX bytes:58 (58.0 B)

* Followed  the Tanzilli instructions to delete the route, now i have:
Destination     Gateway         Genmask         Flags Metric Ref    
Use Iface
192.168.202.0   *               255.255.255.255 UH    0      0        
0 ppp0
192.168.254.0   *               255.255.255.0   U     0      0        
0 eth0

* I am able to keep the telnet connection with the private IP
* I can ping from the foxboard:
ping 189.88.28.174
189.88.28.174 is alive!

* from the internet (my linuxbox) not (even http):
[EMAIL PROTECTED] ~]$ ping 189.88.28.174
PING 189.88.28.174 (189.88.28.174) 56(84) bytes of data.

--- 189.88.28.174 ping statistics ---
27 packets transmitted, 0 received, 100% packet loss, time 25994ms

What  i am doing wrong or missing?
Any suggestion would be really appreciated.

Best regards,
Alexander
