ec2 인스턴스에 ezproxy를 설치할 수 없습니다

Question

ec2 인스턴스에 ezproxy를 설치할 수 없으므로 공용 및 개인용 IP가 있으므로 문제가있는 것 같습니다. 내가

Checking ability to directly connect to iptest.ezproxy.com 
Attempting to contact iptest.ezproxy.com by name 
Connection established, sending my IP address (10.135.235.34) for testing 
Waiting for response on port 0 
The test results follow: 

If you are using multiple IP interfaces on your system, some of 
the information provided by this test may be inaccurate. 

You claim to be ip-10-135-235-34.ec2.internal at address 10.135.235.34 
To me, you appear to be 54.242.97.3 
Since those don't match, there may be a proxy server between us. 

I am now attempting to connect to your server to check for intervening 
firewalls. If there is a firewall, this may take a little while. 

Trying ip-10-135-235-34.ec2.internal 
Connection to ip-10-135-235-34.ec2.internal failed, trying 10.135.235.34 
Connection to 10.135.235.34 failed, trying 54.242.97.3 
Connection to 54.242.97.3 failed 

I am unable to connect to you. There may be a firewall between us. 

Your system claims that its host name is ip-10-135-235-34.ec2.internal 
That name failed to work, which may indicate a problem or may 
have occurred if you have multiple IP addresses on this server.

는 54.242.97.3 공개 IP 주소 URL이 4 단계와 5 단계 오류에 실패 https://www.oclc.org/support/services/ezproxy/documentation/download/install-linux.en.html 에서 설치를 위해이 방법을 사용? 그렇다면 EZProxy가 연결되어 있어야합니다. EC2 보안 그룹을 다시 확인하여 EZProxy에 필요한 포트에서 트래픽을 허용하는지 확인하십시오.

54.242.97.3이 공용 IP 주소가 아닌 경우 NAT 게이트웨이를 통해 연결하고있을 가능성이 큽니다. NAT 게이트웨이 뒤에 EZProxy를 설정하는 지침을 따르십시오.
