Overview
The Multi-Port Forward Server, also known as a port address translation server (PAT), is a virtual appliance designed to efficiently manage inbound UDP and TCP traffic on user-defined ports.
This server forwards the traffic in real-time to either an internal private IP address or an external IP address (NAT), and it can be configured to redirect incoming traffic to user-defined destination ports. With the ability to specify multiple listening ports and forward connections to multiple destinations, this server is ideal for enterprise deployments where it acts as a gateway, allowing the whitelisting of client or third-party firewalls.
The Multi-Port Forward Server allows you to efficiently manage and redirect inbound traffic, making it a valuable turn-key solution to your AWS environment.
Highlights
- Multi-port address translation for internal resources requiring external accessibility.
- Redirects both TCP and UDP traffic to internal or external servers.
- Multiple listening ports can be configured and traffic can be directed to multiple destination hosts.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

Usage instructions
- Edit the /etc/multiportforward/multiportforward.config file using vim, or nano.
- Edit the JSON entries to reflect your desired port forwarding configuration; multiple entries can be added.
- Enter a custom key name for your entry (sshbastion, rdpbastion, etc.); this is can be set to any alphanumeric value, do not use spaces.
- Update the source port (SPORT), this is the port that will be receiving traffic.
- Update the destination host (DHOST) IP address. Typically, this would be a private IP address within your VPC.
- Update the destination port (DPORT) for the traffic to target.
- Update the protocol (PROTOCOL) to either be udp or tcp.
- Reboot the system.
- Ensure that the Multi-Port Forward Server appliance's Security Group permits inbound traffic to the source ports.
- Ensure that source and destination checks are disabled for the Multi-Port Forward Server instance.

Excellent customer support
Thank you Cornel!
I was struggling with the ability to pass UDP packets to a server inside my firewall - nothing seemed to help as UDP cannot be passed over SSH.
Cornel answered my question promptly with a solution that worked quite well - based around the little known but quite useful linux command "socat".
The help is very much appreciated!
SUCCESS AT LAST!
So I had a review on here earlier so this is sort of an update.
When I first tried this it didn't seem to work at all but I may have been wrong all along. It also didn't support UDP so it wasn't what I was looking for. But after contacting the creator I got a reply a little while later and he was more than willing to help me out. Now I informed him it wasn't what I was looking for since there was no UDP support and he told me it was coming in a future update. Sure enough a couple weeks later I got an email letting me know it was available and asking me to try it out. While it took a little while to find the time, I finally did and still had issues. Again the creator reached out to help me, and after 2 different troubleshooting sessions for a total 2.5 hours we got it working.
The creator even did research on my setup and worked with me over email between sessions until we got right. The silly thing is the fix had nothing to do with my hardware but with AWS.
Anyway great product, easy to use, and great support. I highly recommend this and if you run into issues, even silly ones, contact the creator for some awesome support!
