Re: [BEHAVE] Last Call: <draft-ietf-behave-v4v6-bih-06.txt> (Dual Stack Hosts Using "Bump-in-the-Host" (BIH)) to Proposed Standard

2011-09-29 11:09:41
Hello Dan,

Can you run an FTP server on the BIH host, and have it do active mode
transfers and passive mode transfers?

Could you elaborate the scenario? You assume BIH host taking FTP sever.
I'm not sure whether following scenarios are correct

There are two possibilities

Option 1:

+---------------+
|BIH(FTP sever) |----------NAT64-------FTP Client
+---------------+


Option 2:

+---------------+
|BIH(FTP sever) |--------------FTP Client
+---------------+

In the case of Option 1, it can't work since NAT64 couldn't support
IPv4 initiated session

In the case of Option 2, it could work if BIH do ALG


BTW, if BIH takes the role of FTP client, I guess it works in both
active and passive mode when NAT64 do ALG

If there is something wrong, please correct me

Many thanks

Gang
