exeption in proxy forward rule

hello,
i must disable 1 IP in my proxy(squid on other PC) redirect rule

279   ;;; web proxy
     chain=dstnat action=dst-nat to-addresses=EXTERNAL_IP_PROXY to-ports=8088
     protocol=tcp src-address=192.168.1.0/24 dst-address=!192.168.0.0/16
     dst-port=80

and i don’t know how, i cant add 192.168.1.28/30 (dst-address=!192.168.0.0/16, 192.168.1.28/30) to dst-address because winboox says Error in Dst. Address - ip address expected

how can i baypass this ?

Make an address list and refer to that instead.
