Pros/Cons ICE (+) V4/v6 selection dynamic – deals with v6 connectivity breaks – good for transition (+) wouldn’t need to add something for FW/NAT (+) allows path characteristic based v4/v6 selection (+) Can use RFC 3484 with it (-) complex (-) will need ICE even if there is no NAT/FW anymore (+) will be on endpoints anyway ANAT/+ICE (+) ANAT simpler than ICE if you only need static v4/v6 selection (+) already specified (-) Must always use ANAT even when ICE is used too for backwards compatibility - ANAT adds no value there (-) Doesn’t work with RFC 3484 (-) static selection doesn’t allow fallback in case of path problems (-) no path based selection |
