Hello,can you tell me how to resolve this problem: the UE attached,but it cannot have the internet connection

iucgnaw commented 4 years ago

Me too, COTS UE can attach and connect to latest eNB/EPC, but can't bear any data traffic. Even can't ping PDN (12.1.1.1) from UE, and vice veasa.

i have solved it, you should use iptables to NAT some information

Could you kindly share the details how you solve it? Thanks

liyinxin commented 4 years ago

sudo iptables -A FORWARD -i gtp0 -o docker0 -j ACCEPT sudo iptables -t nat -A POSTROUTING -o docker0 -j MASQUERADE like this !

iucgnaw commented 4 years ago

Thanks for quick response! But this seems to solve NAT to Internet. My situation is the mobile phone can connect, get IP address as 12.1.1.2 (using APN default.ng4T.com). But can't ping peer GW 12.1.1.1, not mention other data traffics...

liyinxin commented 4 years ago

iucgnaw commented 4 years ago
