Open issues Port preservation REQ-3: It is RECOMMENDED that a NAT have a "Port assignment" behavior of "No port preservation". NAT MAY use a "Port assignment" behavior of "Port preservation". Not recommending “port preservation” is meaningless because “random” can mean preservation Either we recommend port preservation or we don’t recommend anything at all Proposal: Don’t recommend anything at all (i.e., ports may or may not be preserved: not important) Others? Next step? |
