This was a limitation in my local package filter (nftables), which
only allowed 127.0.0.1 on loopback.  I extended this allow 127.0.0.0/8
and the problems were reduced.
Now acl-multiple-ip-addresses-specified-with-destination succeeds.

acl-multiple-ip-addresses-specified-without-destination was reduced to
two fails:

test 0004...[Request from client address from denied network range]
 
curl returned 52, when expecting 56
 4: exit FAILED
test 0005...[Request from client address from denied network range]
 
curl returned 52, when expecting 56
 5: exit FAILED
test 0006...[Request from client address from denied network range to destination that has an exception]
---d---e--- OK (6   out of 6  , remaining: 00:00, took 0.059s, duration: 00:01)
TESTDONE: 6 tests were considered during 1 seconds.
TESTDONE: 4 tests out of 6 reported OK: 66%
 
FAIL 4: 'Request from client address from denied network range' HTTP, HTTP GET
FAIL 5: 'Request from client address from denied network range' HTTP, HTTP GET
 
TESTFAIL: These test cases failed: 4 5

I didn't understand what's going wrong here, yet.


acl-permit-access-with-exceptions fails on only one test:
test 0004...[Request from client address from denied network range]
 
 4: data FAILED:

Okay, this test expects, that no server is listening on 127.0.0.1:80,
which isn't true on my development machine.  If I stop apache2, the
test succeeds :-)
