Have you tried ip route
and see if the default gateway is configured to 172.16.0.1
?
Yes. We have execute: sudo route add default gw 172.16.0.1 tun_srsue, and as a result we got this:
lab138@NUC8i5BEH:/etc/network$ ip route default via 172.16.0.1 dev tun_srsue 169.254.0.0/16 dev tun_srsue scope link metric 1000 172.16.0.0/24 dev tun_srsue proto kernel scope link src 172.16.0.5
Any suggestion?
Thank you so much
Use mailist please. Thanks
Hi again,
Finally we have connected the UE with a Usim Card (sysmocom) with our two LimeSDR:
Random Access Transmission: seq=19, ra-rnti=0x2 RRC Connected Random Access Complete. c-rnti=0x46, ta=1 Network attach successful. IP: 172.16.0.2 Software Radio Systems LTE (srsLTE)
tun_srsue: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1500 inet 172.16.0.2 netmask 255.255.255.0 destination 172.16.0.2 unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 500 (UNSPEC) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 1 bytes 48 (48.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Then we did a ping from the UE to ENB and it was successful: ping 172.16.0.1 PING 172.16.0.1 (172.16.0.1) 56(84) bytes of data. 64 bytes from 172.16.0.1: icmp_seq=1 ttl=64 time=28.1 ms 64 bytes from 172.16.0.1: icmp_seq=2 ttl=64 time=16.8 ms 64 bytes from 172.16.0.1: icmp_seq=3 ttl=64 time=14.0 ms 64 bytes from 172.16.0.1: icmp_seq=4 ttl=64 time=11.8 ms
But when we tried to do a ping to internet, failed ping 8.8.8.8 connect: Network is unreachable
We don't understand why is not working because with a mobile phone works Ok and we can surf in the internet (The masquerade is done).
Please, help us.
We will grateful.
Thanks
