Re: *** GMX Spamverdacht *** Re: GGSN p-t-p address?

The first tested implementation is Huawei E303, a 3G data modem in the USB stick form factor; it is Qualcomm-based to the best of my knowledge. Here is the ifconfig output: ppp0 Link encap:Point-to-Point Protocol inet addr:21.227.117.124 P-t-P:10.64.64.64 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:33967 errors:0 dropped:0 overruns:0 frame:0 TX packets:29454 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:28077904 (26.7 Mb) TX bytes:2831375 (2.7 Mb) The other tested implementation is my own FreeCalypso, or more specifically an FCDEV3B modem board running FreeCalypso Magnetite hybrid firmware, build date 2018-07-30T20:24:34Z. It is also using a different SIM, although on the same billing account with T-Mobile and with the same service configuration - I am too lazy to move the same SIM back and forth between the USB stick modem and my own board. Here is the ifconfig output: ppp0 Link encap:Point-to-Point Protocol inet addr:22.255.27.2 P-t-P:10.64.64.64 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:285 errors:0 dropped:0 overruns:0 frame:0 TX packets:341 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:79139 (77.2 Kb) TX bytes:35368 (34.5 Kb) The dynamically assigned IP address is different because I had to shut down pppd with one modem and start a new session with the other modem, but notice that the P-t-P address is the same fixed 10.64.64.64.
