> btw, BR also depends upon NAT44 to deal with the unknown protocol, right? if so, may i say your statement "BR will support them without needing an update" is a proposition actually not existing? because NAT44 won't support them without any update. right?

Not right. Only CEs that need to support a new protocol are concerned:
- If a shared address server supports a new protocol, it can be reached via an unchanged BR.
- If a client using a new protocol tries to reach a shared-address CE that doesn't support this protocol, the client will be returned an error message by the destination NAT44.
