[srslte-users] Ue can not connect to the internet when epc is run in the Alibaba Cloud Server

[putaogan]

Dear all，
I want to put epc Alibaba Cloud Server which has a public network, enb  runs in a local server with a public network ip and they can get access to each other.
and i use a phone as ue.
when the epc and enb run , the phone can get a ip such as 172.16.0.2 and it will show a  very slow network speed ,about 1k/s,but it can not connect to the internet. By the way ,i have run the shell  script named " srsepc_if_masq.sh " .
I do not know why it can not connect to the internet and i hope i can get some help.
Here is some information:
1、 Alibaba Cloud Server ： I can find a eth0 interface in it with a local network ip 172.18.151.41 with . In the epc.conf file,i set mme_bind_addr=172.18.151.41 and gtpu_bind_addr=172.18.151.41(the reason i did not use the public network ip is that i will report error when i run "sudo srsepc epc.conf").and i run  another command "sudo ./srsepc_if_masq.sh eth0" .then epc is ok.
2、In the enb.conf file,i set mme_addr as the public network ip of  Alibaba Cloud Server and set gtp_bind_addr,s1c_bind_addr as the public network ip of the local server.
3、epc.pcap and enb.pcap are in the attachment


If anyone has any ideas about this ,please let me know.
Thank a lot.
