First you will need:

Hardware (Required)
Tandy Color Computer 1, 2, 3, Dragon32/64 or Emulator, with at least 64k of memory
CoCo Serial to DB-9 adapter cable. (more on this later or email me)
A Windows, Mac or Linux PC system.
A Monitor/TV for the CoCo
Also for real CoCo's using bitbanger (serial) port, if your PC does not have a DB-9 serial port, you will have to purchase a USB-to-DB9 adapter
  (more later or email me).

That’s it! This is all the hardware it takes to run an efficient modern CoCo system! For optional hardware, there are hundreds of
things that could be listed, but I will only list the standards:

Hardware (Optional)
CoCo Floppy disk controller (Any CoCo compatible will do) - (replaced ROM image for HDB-DOS DW3 - see below)
CoCo Floppy disk drive(s) (35t, 40trk, 80trk)
CoCo Multipak interface
CoCo RS-232 Program Pak (if needed) - (replaced ROM image for HDB-DOS DW3 - email me, tell me which CoCo your using)

Software (Required) - In which I have (you will receive after you register - Welcome File Pack)
You may also need a IP/Port Mapper/Proxy: TCP IP/Port Mapper (Port Proxy) (See below)

config DriveWire Server IP and Port

config MPI to use Slot 1

Hard Reset [F9] Vcc if needed.

XROAR: https://www.6809.org.uk/xroar/

CoCo 1: xroar -machine coco -becker -becker-ip 192.168.0.99 -becker-port 65504
(NTSC): xroar -machine cocous -becker -becker-ip 192.168.0.99 -becker-port 65504

For MAME and maybe real CoCo's (IP/Port Proxy):
For MAME and maybe real CoCo's you will need a TCP IP/Port Mapper (Port Proxy) in which you can also type at the Administrator Command Prompt or Administrator PowerShell on Windows host machine below, for Linux see below that.
or Download (local) the portable version of TCP IP/Port Mapper (Windows - freeware) - TCP-IP-Mapper-portable.zip
or go to my other web site https://www.markallenby.net/ and download it yourself, portable or install version.
You may also need to download (local): .NET Framework 2.0 Because TCP-IP-Mapper uses it.

Port Proxy

Windows:

Administrator Command Prompt or Administrator PowerShell (IS REQUIRED):

To Create:
netsh interface portproxy add v4tov4 listenport=65504 listenaddress=127.0.0.1 connectport=65504 connectaddress=192.168.0.99

To Delete:
netsh interface portproxy delete v4tov4 listenport=65504 listenaddress=127.0.0.1

Linux:
Install socat Under Debian / Ubuntu Linux

Type the following command:

$ sudo apt-get update && sudo apt-get install socat

To redirect all port 80 conenctions to ip 192.168.0.5, enter:

$ socat TCP-LISTEN:80,fork TCP:192.168.0.5:80

All TCP4 connections to port 80 will be redirected to 192.168.0.5. This is just like netcat.

You can terminate connection by pressing [CTRL+C] i.e. ^C.

For more Info on socat: http://www.dest-unreach.org/socat/

OR

IP Tables:

1. Allow packet forwarding

echo 1 >/proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -j MASQUERADE
iptables  - A   FORWARD  - i  [ Intranet card name]  - j   ACCEPT
iptables  - t   nat  - A   POSTROUTING  - s  [ Intranet segment]  - o  [ Name of external network card]  - j   MASQUERADE

Example:

echo 1 >/proc/sys/net/ipv4/ip_forward
iptables -t nat -A POSTROUTING -j MASQUERADE
iptables -A FORWARD -i ens33 -j ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.50.0/24 -o ens37 -j MASQUERADE

2. Set port mapping
iptables  - t   nat  - A   PREROUTING  - p   tcp  - m   tcp  -- dport  [ [Internet port]  - j   DNAT  -- to-destination  [ Intranet address]: [intranet port]

Example:
iptables -t nat -A PREROUTING -p tcp -m tcp --dport 6080 -j DNAT --to-destination 10.0.0.100:6090

3. Save settings (Permanent)
service iptables save
service iptables restart

When you load Serial-TCP in windows select:
▪ Your COM Port
▪ Operating Mode: Bridging
▪ TCP/IP Settings: TCP Client
▪ Remote IP: [as assigned to you when you registered]
▪ Remote Port: [as assigned to you when you registered]
Click Activate!
