I have my Graylog server on Amazon environment.
I can collect the logs from client/server to Graylog server using the internal IP address with GELF UDP.
my clients are using nxlog to send the logs to Graylog server.
But when I try to use the Public IP address of the Graylog server in the client and try to get the logs unable to get them from the client/servers.
My Setup is on AWS with VPC.
I had set up gray log server in VPC
and I had a windows client on Default (not is VPC) network,
I had allowed Security Groups to allow incoming and outgoing network for port 12201.
still unable to get the logs from the servers.
