Hi,
I have a RB760iGS board. I have default configuration:
- ethernet 1 is WAN
- ethernet 2, 3, 4, 5 is bridged on my lan

My LAN is 192.168.0.0/24
My website: http://MYDOMAIN.COM that is connected with my internal server 192.168.0.67

If I connect to http://MYDOMAIN.COM from WAN (eg my smartphone with mobile network) everything works.
If I connect to http://MYDOMAIN.COM from LAN, it is unreachable.

I created a srcnat rule, but it doesn't work Now, because I have several services on my server 192.168.0.67 (80, 443, 21, etc etc) reachable using MYDOMAIN.COM, is there a way to enable all of them in order I can access from LAN using domain name?

Thanks

Either have split DNS (so that it returns LAN IP addresses to LAN clients) or configure hairpin NAT.

Sounds like hairpin nat scenario.

Modify nat rule to this (assuming your bridge is called LAN)
