What on earth am I doing wrong? [SQUID 3.4.8]

[squidmakingmyheadexplode]

There are multiple I.P's on my server which I want to use for proxies. Access only allowed by a specific I.P.
But whatever I try, all connections are accepted. I want it only to be accessed by the I.P specified as 'AllowedClientIp'

This is my config file:

http_port PROXYIP:PORT name=1
http_port PROXYIP:PORT  name=2
http_port PROXYIP:PORT  name=3

acl een myportname 1 src AllowedClientIp
http_access allow een
tcp_outgoing_address PROXYIP:PORT een

acl twee myportname 2 src AllowedClientIp
http_access allow twee
tcp_outgoing_address PROXYIP:PORT twee

acl drie myportname 3 src AllowedClientIp
http_access allow drie
tcp_outgoing_address PROXYIP:PORT drie

http_access deny all
