Hi all. I was testing cells and installing following the documentation: [https://pydio.com/en/docs/cells/v1/requirements](https://pydio.com/en/docs/cells/v1/requirements) [https://pydio.com/en/docs/cells/v1/debian-systems](https://pydio.com/en/docs/cells/v1/debian-systems) After installing I was unable to start cells. Some kind of networking error. Mentioned documentation newer mentioned 2 networks, so I got stuck. Don’t know exactly why but I added an alias on eth0, named eth0:1 with private ip range and the cells started? Any links to documentation about 2 networks requirements would be appreciated? Regards ---

PS. Some time in next week I’ll redo install and copy the error messages. ---

Thx for the info @c12simple That is just stupid from the developers!!! I have a machine directly on public network, but cells require additional private address? Why would I need to have private IP network? I’m trying to figure that … They should specify that in requirements, not in troubleshooting. ---

Hi, It comes from NATS service which works only in local network because of security reason. ---

THX again for clarifying the situation for me. They really should specify that in requirements documentation, and not in troubleshooting 🙂 ---

This is really strange. If cells needs some kind of local network (for “security reason” or whatever) then cells could use localhost / 127.0.0.1, but we should really not be required to setup a random ip alias, to allow cells to start… ---

@ginawu45 @c12simple I agree, it is strange. If it’s for security reasons why not 127.0.0.1? Why force aliases? Let me rephrase: Why not document it, as it is currently required, in [https://www.pydio.com/en/docs/cells/v1/requirements](https://www.pydio.com/en/docs/cells/v1/requirements) because it is a REQUIREMENT!!! PS. Thanks to whoever added it 🙂 ---

Hi, i will add an instruction in the networking section about it. ---

The mention about an additional private network never made it and it’s still a big installation issue one year later with v2: > [@\`./cells install --bind\` on VPS, LetsEncrypt and reverse-proxy](https://forum.pydio.com/t/cells-install-bind-on-vps-letsencrypt-and-reverse-proxy/3102): > > It’s basically a dedicated post to deal with the last comments on: [https://forum.pydio.com/t/url-doesn-t-open-during-cells-installation-process/2954/12?u=drzraf](https://forum.pydio.com/t/url-doesn-t-open-during-cells-installation-process/2954/12) I’m having hard time figuring out the right value of the --bind parameter during ./cells install Configuration: VPS (no virt) Cloudflare (I want to keep IP address privacy behind their proxy) DNS A record set --external will be set to https://my.domain.org (resolvable) one external IP (v4 & v6) address a loopback iface ==\> Pretty s…
