KPA1500 - Static IPv4 address

Is it possible to set a static IP address on this amp? I am thinking using one of my static IPv4 address and port 1500. This would eliminate the local /server computer.
Or is there a better method of using remote K3, KPA1500 and RemoteRig? I want to be able to use the KPA1500 app to monitor the amp.

Burl, AJ9Q

Re: KPA1500 - Static IPv4 address

I set the IP by using the facility in my router to assign a fixed IP to a MAC address. Using the "KPA1500 remote" software I can access the amp on the local LAN via Ethernet or via the USB connection.

I have not been able to access it remotely via the Ethernet interface by forwarding an external port to the KPA1500 IP address and port, so I use the USB interface and then Windows desktop connection to accomplish remote control. This is okay for one person access, which is all I need. The software should provide multi-user access, but I have not been able to achieve that so far.

Re: KPA1500 - Static IPv4 address

I have a Raspberry Pi 3 running OpenVPN to solve exactly this kind of
problem.

OpenVPN lets you connect remotely from the outside world and actually
get an IP off of your own LAN.

The best thing about this is you aren't opening ports that *might* be
vulnerable to some exploit -- other than the Pi, but at least it's a
single point of attack.

You don't have to be a Linux expert to do this, you can pretty much do
this in cookbook fashion successfully.

Once installed, you also get access to any NAS boxes, your home printer,
etc. from anywhere -- the VPN is just like a really long ethernet cable.

Eventually, I'll get FLDIGI running on the Pi, when time permits, and
have everything I need to run digital from anywhere inside or outside my
home.

Yes. You can disable DHCP in the amplifier and assign a static address.
Your router must be capable (within its address range) of accepting that
static address without a conflict from another device.

In the KPA1500 configuration utility v1.18.7.9:

Select menu >Configuration >Edit Configuration >Network tab
On the network tab, disable (uncheck) DHCP
Manually enter the address you want the amplifier to use
Press <Apply >OK.

I have to second the VPN solution. I have a similar setup with an incoming
VPN. You can be anywhere in the world with a computer or mobile device and
connect to your home network and have access to everything as if you are
there.

I also use OpenVPN, but on a larger Linux computer. It also can be run on a
router with DD-WRT or even on a commercial router designed for this
purpose. There are other VPNs also.

If you do port forwarding, anyone on the internet can access your KPA1500.
As far as I can tell, it is not meant to be connected to the internet.
There is no security or password protection. And, someone will figure out
how to do bad things. There are just people like that out there. I
generally think port forwarding is a BAD IDEA! Many security and baby
cameras that use port forwarding have been hacked. There are even automatic
search engines to find them.

A VPN on the other hand provides pretty good security. The VPN server runs
on a computer on your network. A client runs on the remote device. It
generally requires something you know (a password) and something you have
(a digital certificate on the client ). So, for anyone to get in, they need
both your client device and the password. You can revoke a stolen digital
certificate and create another if needed. There have been vulnerabilities
on VPNs, but they get patched and if you keep updated, you are certainly
better off than using port forwarding.

There are a couple drawbacks though. Your ISP may block some incoming
connections. I also would say that I did successfully set it up, and it has
worked for years with no problems, but it was not simple. There are
cookbooks to do so, but they are long cookbooks. A commercial router with
this capability may be better if you don't feel so inclined..

Good luck in whatever you do.

73,
