Here, I'm redirecting all HTTPS traffic *except* the one that goes to my bank: iptables -A PREROUTING -t nat -i $IFACE_LAN -p tcp ! -d www.credit-cooperatif.coop --dport 443 -j REDIRECT --to-port 3129 This works because my bank is hosted on a single IP. As soon as I replace that with a domain that's hosted on multiple IP's, I get this: iptables -A PREROUTING -t nat -i $IFACE_LAN -p tcp ! -d www.google.com --dport 443 -j REDIRECT --to-port 3129 # firewall.sh iptables v1.4.21: ! not allowed with multiple source or destination IP addresses So my question is: how can I write an iptables rule (or series of rules) that redirect all traffic to my proxy, *except* the one going to <list_of_domains> ?
