Cannot access jail from outside network, even after port forwarding

[stevenpgrey]

I've installed the Nextcloud plugin and hoped to use it outside, but no matter what port I use, it can't be reached.
Maybe my ISP has blocked port 80? But nope, when I temporarily point 80 to Truenas itself it works. Seems that my other jail (Transmission) has the same issue.
My jails have NAT disabled, and take up a spot on my local network. VNET is enabled. I haven't done anything else than give it an IP address and set a default router.
Thanks.

Next cloud uses port 80(http) as a fallback, try using 443(https), which is absolutely necessary when you pass traffic through the internet anyway.

You might see a warning about the nextcloud certificate, just ignore it.

As for transmission, the torrent P2P protocol heavily relies on IPv6, you should configure that, too.

Also check your router's firewall. Sometimes doing a port forward does not mean that the firewall allows the ports automatically.

As for the ISP, most Residential and SOHO ISPs block the small-numbered ports by default. Try calling them, most have a scheme for disabling their firewall.

I am sorry for the many posts, but there is much to unpack here. Do you have access to any jail from your local network?
