Networking on a Mac

I’ve now successfully got Webster and Netsurf working so decided it was time to check that some of my websites still work on RISC OS browsers. I’ve configured my networking using exactly the same parameters as my Iyonix (apart from ip address and computer name) and rebooted. Result:

Machine startup has not completed successfully: ‘Route: add net.default: gateway 192.168.2.1: Network is unreachable’.

Any suggestions gratefully received.

Have you followed the instructions in the ReadMe about all the extra stuff you need to install on the Mac side? (tuntap etc.)
