Connect Companion to a IPFS node

Help
1

ipfs version: 0.8.0

Hi everyone,

this is an often requested question but I still couldn’t find help in the existing threads so far. My IPFS node runs on a dedicated machine in my intranet, let’s say it’s found here: 192.168.1.2.

The node has plenty of peers, see ipfs swarm peers and I can locally access the webui.

I understand the following settings must be met in order to access the node from another machine int the intranet:

ipfs config Addresses.API /ip4/0.0.0.0/tcp/5001
ipfs config Addresses.Gateway /ip4/0.0.0.0/tcp/9001
ipfs config --json API.HTTPHeaders.Access-Control-Allow-Origin '["*"]'

I don’t expose the machine to the public, so this is fine with me.

However, I still cannot access the webui from any other machine in my intranet. When calling http:///192.168.1.2:5001/webui it simply gets a

--2021-05-22 14:37:02--  http://192.168.1.2:5001/webui
Connecting to 192.168.1.2:5001... failed: Connection refused.

I don’t know what else to check for and any help would be appreciated.
The machine is of course reachable and I can ssh into it without problems.

Greetings

To be more specific: Running

curl -X POST “http://127.0.0.1:5001/api/v0/swarm/peers”

on the node itself works but

curl -X POST “http://192.168.1.2:5001/api/v0/swarm/peers”

doesn’t.

Okay, this was sufficient hint to myself to stop making a fool out of me.

I started my IPFS node via docker explicitly only opening the port 5001 8080 for 127.0.0.1. Simply don’t do that and it should work.

Now I’m on to new problems. It seems my ISP shuts me out everytime I spin the node up :confused:
