What did you change?

What's that first rule supposed to do?

Where is this? this "su-3.2" is a bit confusing, would be useful to set
your hostname to "jail" within the jail...
I think it is typical for jails to clone the loopback interface for this

Use tcpdump, you should see if your rdr/map rules work as expected.
Also, pfctl -ss and similar.
Can you ssh from the host system to the jail?
If nobody replies, maybe try to rephrase your question, investigate
further and provide additional information rather than just repost.
