Dear srsLTE team
I run srsue on a machine, enb+epc on another machine. LimeSDR USB are
RF end on both sides.
I try to use chrome to open www.google.com on UE machine. But i failed.
I did:
1\ UE attached the eNB. UE got an IP address :172.16.0.2
2\ use command on UE:
sudo route add default gw 172.16.0.1 tun_srsue
3\ use command on epc:
sudo ./srsepc_if_masq.sh wlp2s0
on ue:
