Pretty new to Nethserver and Linux overall. I seem to have setup a working e-mail server that can send e-mails to the internet and receive e-mails from external domains. However I cannot, for the life of me, seem to get Roundcube configured to be reached outside of my network at webmail.domain.eu.
Also adding IMAP to gmail on Android says that the server cannot be found.
Sadly I’ve tried on multiple browsers and multiple devices, still no bueno.
I’m starting to think that it might be due to the fact that I have NAT behind NAT at the location where the server is hosted. My try it in my homelab first, don’t have static IP but for troubleshooting should be good.
