Andreas Mueller andreas.mueller at criticallabs.org Hello,
I tried to use a Huawei E1823 UMTS-Stick on a debian8-laptop with wvdial and pppd to connect to a nano3G for getting an IP/Internet-connection via UMTS/HSDPA.
The setup is mainly as described on http://osmocom.org/projects/cellular-infrastructure/wiki/Getting_Started_with_3G.
When using an android-Smartphone with the same configuration of the ggsn and the other components the IP/Internet-connection is working.
After pppd is started from wvdial it receives his local IP-address from the "net 192.168.99.0/24" parameter of ggsn.conf and also the configured DNS-Server, but no remote-IP, so 10.64.64.64 is used by pppd as a default value:
...
--> local IP address 192.168.99.5
--> pppd: �[7f]
--> remote IP address 10.64.64.64
--> pppd: �[7f]
--> primary DNS address 8.8.8.8
--> pppd: �[7f]
..which results in an unusable ppp0-device:
ppp0 Link encap:Point-to-Point Protocol
inet addr:192.168.99.5 P-t-P:10.64.64.64 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1
Has anybody successfully used an UMTS-Stick with ggsn?
How can I tell ggsn to send his IP-Adress, which can be used by pppd as "remote IP address"?
Are there special options for pppd which I have to use?
thanks and greetings,
Andreas
