I use a Rapsberry Pi as a WLAN to Ethernet bridge to connect my Indigo2 to the Internet. A tutorial can be found on https://willhaley.com/blog/raspberry-pi-...et-bridge/

For file exchange, I use proftpd running on the Raspberry as well. I have enabled anonymous access by correspondingly adjusting /etc/proftpd/proftpd.conf

Using this setup, I can access the ftp from IRIX with the ftp command and from Win10 or MacOS using Explorer or Finder respectively.

This works very well in my home network. I did not do any security audit though, so I am not sure whether this setup can keep your data safe - although anything involving IRIX must probably be considered "open access" for security purposes due to the lack of security updates and outdated encryption standards.
