My modem broke and I thought (since it used to work) I would connect the OPN-PC. It did not.

You mentioned 'NBN' previously.

If your NBN modem broke, you lost all Internet until NBN replace it, with or without OPNsense.

If your ISP-provided router broke, OPNsense can replace it.

As per @cookiemonster's suggestion, if it's the router, you should take some pictures of your equipment to provide more clarity.

Thank you.

ISP modem is broken.

The set up is 2 PC and they are connected to each other with 1 ethernet cable.

It used to work...but not now. But as I said I can connect to the OPN-PC via its network hole. The new (that used to work) dual network card appears NOT to be working.

Perhaps as we try and fix. I just use the one port that works and set up a static IP for my main PC?? How is that done?

[cookiemonster]

perhaps some clarity is useful.
A connection that requires a modem. A modem is hardware that establishes a connection with the ISP using credentials. OPN can not do that in software.
I think you are saying you moved house and you had a PC with two NICs for OPN and that used to work and now it doesn't but whether in both places or just the new one, you had a modem and now you don't (it broke).
If all this is correct, and your ISP connection requires a modem, you will not be able to get out to the open internet with only OPN. There is no software in OPN that can replace a physical modem.
Take pictures, and will be easier to confirm or you'll be left without hairs.

Thank you.

I have OPS-PC with its original Network socket – is this a NIC??? It is Rj45. I put in another Network card with 2 holes. This was working and so was the internet and the network. Now the card does not work. I have a few spares….but I have a success but no idea is this is good or bad

I have been able to connect to the OPS-PC via the cord into the original RJ45 socket.

I logged on to OPNSense and left all the defaults. Is this good or not?

I cannot have internet and the OPS-PC connected. So I have to disconnect the OPS-PC and connect to the internet to get help from you guys.

What should my next move be?

Perhaps the dual network card sockets should be connected to my NBN modem??

I keep having to reinstall the internet connection.....

The green cable looks like an RJ45 cable, so in the PC that is a NIC. So that matches what you are saying.
That is one part of the chain only though. I was hoping for pictures of the various pieces of hardware.
Find out from your ISP, do you need a modem? Not all connections require one. Which type of modem and what are their credentials used and required.
Quick look https://www.nbnco.com.au/learn/device-compatibility/vdsl2-modems . Is this your provider? You can see they have different requirements depending on connection/broadband product taken.
You need to be clear on what you have and need before you can figure out what needs to be done. Draw it in your mind:
ISP terminating device on the wall --> modem? --> OPN WAN --> OPN LAN -->

One more time: If you need a modem and don't have one, it will never "work".

[Patrick M. Hausen]

Deducing from their screenshots I suspect the "modem" that broke was in fact a router and that further the remaining ISP device delivers a CGNAT address via DHCP.

The problem seemed to be that whenever they connected all of the devices (remaining "modem", OPNsense and PC) at the same time the PC would get an address in the 100.69 range from the ISP device and not be able to communicate with OPNsense. Of course not.

That's why I insisted to connect only OPNsense LAN (or each port in turn until it is evident which one that is) and the PC and nothing else.

But they refused to follow that line so I have no clue what is really happening, just like everybody else, obviously.

[cookiemonster]

yes, I was curious when I saw an external CGNAT ip. Assumed due to house move/service change.
No idea without more and more informative info.

Hi guys.

Thank you all for your help. It has been great.

To answer one of your questions, I have the NBN (fibre to the kerb). I have a white box with 3 lights in the house that is connected with wires to the NBN, into which I plugged in another box Netcommwirelss NF4V that was then connected to a switch and to the various PCs in the system.

As the modem/router or whatever the Netcommwireless box is, would no longer display/transmit the internet, I have now put a PC with Opnsense in its place.

I have managed to get it to work on minimal settings. Just set up 5 static IP addresses, sort of. My main PC should be XXX.XXX. X.144, but it is now 100. So, I have no idea what happened. 144 is nowhere in the network.

I would like to set up some protection, I think that is a Firewall and a VPN. But as I researched this on the internet, it total confused me.

My system is only me, so no vLan (not sure what that is used for) and I just need an idiot’s step-by-step guide to basic set up.

I also used the old Netcommwireless thing as a Wi-Fi hub/accesspoint/bridge/thing and it seems to work. Please do not ask me to repeat the operation.

I have the internet and I can see all my PCs on the network.

Thanks…. Still would like to pursue protections whatever they are for small guy.

[Patrick M. Hausen]

A newly installed OPNsense comes with all the protection you need enabled by default for a small home network. Unless you actively mess up the configuration.

Also why do you care about the IP addresses of your client systems? They will get one from OPNsense via DHCP. There is no need to assign static addresses.

[foxint]

Hi Patrick

Thank you.

I have static IP addresses because I synchronise my data each night. So, they need constant addresses – so I thought. I also use Tight VNC to control the PC’s as they are headless with no monitors, keyboards and mice. They sit in another room.

I am still worried that my main PC that should have a 144 IP is now 100?

I hope I did not mess up the installation.

Good to have some functionality back. FYI, there is not a single modem/router for sale in the whole town. So Opnsense was my only option. All the relevant shops no loner sell these items. I told you I live in Shitsville far from the back of beyond.

[Patrick M. Hausen]

You can navigate to Services > DHCPv4 > Leases, check the IP addresses of your client systems, and by clicking on the small "+" on the right hand side assign a static IP address to your PCs.

Note that static assignments must be outside the dynamic range. You can check the dynamic range (IIRC it starts at .100) at Services > DHCPv4 > LAN.

So e.g. give your PCs addresses .11, .12, etc.

.1 is used by OPNsense already, so don't start at .1.

The fact that your PC used to be .144 and is now .100 does not matter, but if you need static entries, they must be smaller numbers than the start of the dynamic range. It's just numbers, every router/firewall product comes with different defaults.

[foxint]

Hi Patrick,

Thank you again. I am glad you and the other guys are here to guide me.

I am a little confused.

I think my IP range is 192.168.1.1 to 192.168.1.254.

1.   192.168.1.144 is in my mind within the range, so why did it not take?
2.   192.168.1.20 is my old NetcomNF4V, but it remains on 192.168.20.1 – not an issue, but I did try and change the IP from within the Netcom interface, but it did not work. I thought that Opnsense could fix, but not.

It would be nice to have the IP’s as previously intended.

really?

this cant be real can it... troll much?
