@david, I do not see a grin-server.toml file as part of Grin++. What config file does Grin++ use where I can specify the peers_preferred? Thx.

I just realized I cannot setup additional nodes due to the need for port forwarding for port 3414 :sweat_smile:. Since I forward the ports used by Grin to one computer cannot redirect to another, right? I was even thinking of going for three nodes by adding a node running on a Raspberry Pi. Any thoughts on how to circumvent this limitation?

Don’t stop using Grin++ to participate :slight_smile:

But, if you are on Windows I can recomend you setting up a Grin-Node under Windows following my How-To: https://github.com/MCM-Mike/grinnode.live/blob/master/documentation/node/winodws-how-to-run-node.md to run a Grin-Node and connect to us. (not 100% ready but it will guide you through the steps)

You can also share this link and I am writing on an official Windows Grin-Node article here on the main repository: https://github.com/mimblewimble/docs/wiki/(draft)-How-to-run-a-Grin-Node-(Windows) (also in draft state)

As always have fun :smiley:

I would love to do so, but I cannot run two nodes from the same IP right? Nor additional nodes via the same router since I can only forward port 3414 to a single machine.

To not repeat my self again: " Don’t stop using the Grin++"

Using the Grin-Node under Windows (see my how-to) you can add the preferred_peer .

i have successfully setup 2 Grin-Nodes and connected both to Grinnode.live.

Hard to win when you are late 2 the party but im still gonna try! :slight_smile:

Exactly, you can always win an awesome T-shirt. And if you do not win one, you can buy one to ease the pain of not winning. I also put two nodes online.

Hi @david - I have relatively recently set up a grin node, and also started opening up port 3414, and noticed now there is indeed incoming traffic.
My question is exactly what is the difference between incoming and outgoing traffic.
It seems like now much more incoming peers.
Thanks!

Hi @quotha!

It’s great to hear that you’re allowing incoming connections. This helps create a more decentralized and more reliable p2p network.

When you want to join the grin network, nobody knows about you yet, so you need to establish some “outgoing” connections first (connections that you initiate). There are peers called “seeds” which are usually the first peers you connect to. These peers are always “listening” for other nodes to connect to them, which would become “incoming” connections (peers that connected to you).

There’s a limit to how many peers a node will allow to connect to them at any single time, to avoid overusing their resources. So if only a few peers are setup to allow incoming connections (ie. to listen for nodes to connect to them), if all of their allotted connections get used up, new nodes will struggle to find others to accept their outgoing connections when joining the network. This is why it’s important for the network to have lots of people, like yourself, who are allowing incoming connections.
