雙外網IP-StunServer-AWS-EC2

EC2 instance with 2 IP addresses

My general notes on how to do this:

Launch a new EC2 Instance. Follow the launch steps as follows

Step 1: Select a new Ubuntu instance

Step 2: Select instance type (t1.micro is fine)

Step 3: Network configuration

Select the VPC to launch this instance into

For subnet, select the subnet associated with the VPC

For "auto-assign public IP", select "disable" (we'll use an elastic ip to connect later)

For the eth0 adapter, add two static IP addresses not already in use on this subnet (e.g. 10.0.0.20 and 10.0.0.21). Both on eth0. Do not add eth1.

Launch instance.

Associate two elastic IP addresses with this VPC instance. One for the first IP (10.0.0.20) and another for the second IP (10.0.0.21).

Log into this machine on it's primary IP with the elastic IP associated with it.

While logged into this instance, etc /etc/network/interfaces file. At the bottom of this file add the following:

iface eth0:1 inet static

address 10.0.0.21

netmask 255.255.255.0

Then run "sudo ifup eth0:1"

quick script to getting stunserver working on EC2 instance

Following steps work for Ubuntu server on EC2

First, get second interface up and going

edit /etc/network/interfaces

add "eth0:1" to the "auto" line

add:

    iface eth0:1 inet static

        address 10.0.0.xxx

        netmask 255.255.255.0

Reboot required to fully validate. "ifup -a" to bring up eth0:1 before the reboot

Now get the code compiled and running

sudo apt-get update

sudo apt-get install g++

sudo apt-get install git

sudo apt-get install make

sudo apt-get install libboost-dev

sudo apt-get install libssl-dev

git clone https://github.com/jselbie/stunserver

cd stunserver

make

./stuntestcode (confirm all pass)

sudo cp stunclient /usr/bin/stunclient

sudo cp stunserver /usr/bin/stunserver

edit /etc/rc.local to launch /usr/bin/stunserver&

reboot via control panel
