i cannot explain why the routing does not working but you can work in your local network with your server do omething like this:
Don´t work with the external IP adress, rather work with domain names.
You have checked the dns and working fine (external) check it with anoter internet connection (like smartphone)
If DNS in the internet work fine, so your server is working in the i-net.
So you can use an internal DNS and bind your domain to your loacal ip adress 192.x.x.x
or
make an host entry
192.x.x.x. yourdomain.de
in
windows: C:\Windows\System32\drivers\etc\hosts (run editor as administrator/als Administrator ausführen and load the host file)
linux /etc/hosts
on all your local net clients.
This are the steps i am working since 2002 and serving services at DSL Deutsche Telekom.
Today iam working with static ip.
If you want a serious service take a business product 20€ higher and static ip. Further you can work with an accepted smtp relay.
You can setup a lots of domains like registering and delegating to your static ip.
and... don´t work unencrypted - use SSL to prevent other errors.
