Hi,
I installed Tailscale on a RUTX50.
The RUTX50 has 192.168.2.1 ip address.
I activated the Tailscale routes in the 192.168.2.0/24 subnet.
I have a Ifm PLC (having a fixed ip address: 192.168.2.10) that I can connect to (using a software called Codesys) when I’m phisically connected with the ethernet to the RUTX50. But when I connect using Tailscale, Codesys cannot connect anymore to the PLC.
When connected with Tailscale I can ping 192.168.2.10, but I cannot connect to the PLC using the Codesys software. I thought that is was a firewall issue.
I know that these ports should be used by Codesys to connect to a target machine:
How can I setup correctly the RUTX50 firewall to make the Tailscale connection work?
Here is my actual firewall configuration:
Do you have any suggestion how to make it work?
Best regards,
Vincenzo
