I wanted to run this by you before calling it a bug and wanted to see if anyone could propose a workaround.
I have a latest Shibby running on a NT-N66U. My configuration is the following:
- WAN access with public IP
- LAN1 private subnet 192.168.100.x where all the servers are connected to
- LAN2 public subnet 192.168.1.x where all the guest clients are connected to
Now, on LAN1 I have a service (Plex server in this case) that exposes itself via UPnP port forwarding to the internet.
If I try to access it from the outside of my network everything works fine. Of course, if I try to access it from LAN1 using the public IP, works fine too as the NAT Loopback is enabled (with loopback ALL and target MASQUERADE).
Interestingly though, if I try to access from LAN2 using the public IP, the access is denied (the connection doesn't go through). If I give to LAN2 access to LAN1, then connection is fine.
I also tried changing target to SNAT with no luck. I also tried to set a static port forwarding
Does anybody know what the problem could be? I would think that LAN2 would at best have the same limitations of being outside.
Thank you in advance,
