Hi there,

I'm trying to set up a Nextcloud server, and I would like to connect with the public IP / DDNS using the TD-W9970 and DECO E4.

The Nextcloud instance is a TrueNAS jail / plugin, and the TrueNAS is virtualized through Proxmox.

The way I want it to work is through double port forward, i.e.

1. Port forward device (port 443) - DECO E4 (port 15555 or something arbitrarily chosen)
2. Port forward main TD router (port 15555 open) - forward to the DECO address on TD's network

I can connect to the Nextcloud instance using the device ip on TD's network : 15555, but can't use static ip :15555. If I am connected to another network though, I can connect to Nextcloud using static ip.

Is this because TD isn't actually supporting proper NAT loopback (I can connect to router's config page by inputting my static ip though), or is the DECO E4 actually the culprit here?

Thanks!
