I'm trying to connect to my VPN server on OS X server. I have a Linksys WRT54G v. 3 router with the latest Tomato firmware. All the relevant ports are open, but Apple's documentation says that "IP Protocol 50" also has to be open. I understand that some routers don't support IP Protocol 50 passthrough. Does anyone know if Tomato firmware does and what, if anything, I have to enable or configure? TIA.
