YateBTS / GPRS problem in YateBTS
« on: August 11, 2014, 01:44:50 AM »
My cellphone can successfully registered in YateBTS. Voice call and SMS are both OK. But GPRS service has problem.
I read the GPRS throubleshooting page. http://wiki.yatebts.com/index.php/GPRS_Troubleshooting
My cellphone status is:
1) It got IP address 192.168.99.1.
2) I ran “tcpdump -nn -i sgsntun”. There is only uplink traffic, no downlink traffic.
3) I tried to "ping 192.168.99.1" from PC side. There is no response. And the yate.log output is:
<mbts:MILD> miniggsn.cpp:441:miniggsn_snd_npdu_by_mgc: ggsn: Packet failed test, discarded: (packet_dest_ip_addr & rp->ipMasknl) != (rp->ipBasenl & rp->ipMasknl)
What configuration is wrong? What configuration is wrong? NAT problem? How should I configure it?
Thanks
