Allow Any Protocol for Access Ports?

[DWDuq]

I'm trying to let a program though my firewall that uses its own protocol (not TCP or UDP) to start some connections, but cannot figure out how. It seems like this is controlled by the "Access Ports" field for which I seem to only be able to specify either tcp or udp. Is there a way to specify any protocol for a particular port there? E.g. */1234 to let any traffic to port 1234 though.
