Sorry I might have misunderstood, you mentioned giving others access externally and it working fine. Normally, if you’ve set up the service to be publicly accessible on the internet, you can just visit the same site through the public DNS record and your public IP. At home or elsewhere, it’s all the same internet.

So either you’ve done something odd, or you’re talking about different, more private, internal only services?

Can you live with the services routing out and back into your public IP? If it all works for external users on the internet, doing nothing special should mean it works for you too?

Maybe you should
