I need add to my docker network which I using for squid, outgoing ip range from xx.ip to yy.ip.
At the moment I adding single ip using bellow command:

iptables -t nat -A POSTROUTING -s 172.18.0.0/16 ! -o bridge-coi -j SNAT --to-source 1xx.xxx.xxx.xx4

How I can add range ip?

When I put several many above command, not working.

Docker networks have no restriction for outgoing traffic. Are you trying to restrict outgoing traffic from your containerized squid to a specific ip-range?
