[Jool-list] DNAT "port mapping" through jool? [EXTERNAL]

[Art Cancro]

Manual entry to bib table looks like the right approach.   I tried it today.  100.127.255.253 is the interface on the IPv4 side of my jool machine, and we are successfully doing NAT64 of a /96 block towards the IPv4 side...

So as a test I am trying to see if we can get clients who connect to 100.127:255:253#80 to get the HTTP server at 2607:f8b0:4002:c02::8a#80 (which is google, but again it's just a test)

So the command appears to be:

jool bib add --tcp 2607:f8b0:4002:c02::8a#80 100.127.255.253#80

And the error response is:

Error: The kernel module returned error 22: The transport address '100.127.255.253#80' does not belong to pool4.  Please add it there  first.

So I tried:

jool pool4 add --tcp 100.127.255.253 80
jool bib add --tcp 2607:f8b0:4002:c02::8a#80 100.127.255.253#80

This works for outbound connections, but it broke the NAT64 inbound connections.

Does jool support pool6 IPv6-->IPv4 and manual bib IPv4-->IPv6 at the same time?

Woops, I meant

sudo jool bib add cafe::1#80 203.0.113.1#80
