I've experimented some more, and I have a partial success. 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> ?

Cheers,

Niki
