Fred, technically speaking NAT for forwarding packets with protocol field 41 is the same as NAT for forwarding packets with protocol field 6 (TCP) and 17 (UDP). Well, the entities in the NAT table are different, e.g. for 41 it's
 (source IP address, target IP address, IP protocol) 
whereas for 6 and 17 it's
(source IP address, source TCP/UDP port, target IP address, target TCP/UDP port)
but the principle of address translation is the same. The difference in the entity comes from the fact that 41 forwarding happen on IP layer  whereas the 6 and 17 forwarding happen on TCP/UDP layer, taking into accoun the ports numbers as well. 
 
Frankly speakning I do not see any reason to go for another name.
