Hi, folks
Netfilter added a shifted port range mapping function in Linux kernel 4.19, it looks like this: iptables -t nat -A zone_wan_prerouting -p tcp -m tcp --dport 5000:5100 -j DNAT --to-destination '192.168.1.2:2000-2100/5000' 5000-51000 is mapped to 2000-2100 Can ovs ct action do this? If not, can it do the below case? iptables -t nat -A zone_wan_prerouting -p tcp -m tcp --dport 5000:5100 -j DNAT --to-destination '192.168.1.2:5000-5100' I’m wondering how we can use openflow to express this precisely, tcp dport range expression is also a big problem.
