How can I redirect one port to another local port by using ip6tables ? e.g. something like this : ip6tables -t nat -A PREROUTING -j REDIRECT -p tcp --dport 443 --to-ports 8443<
ip6tables
does not support REDIRECT
. (Normally people use this in a NAT environment, and NAT is generally not supported with IPv6.)
If all you need to do is bind to the low port as a normal user, why not try the workaround described in this answer? Of course, in the case of Tomcat, it sounds like this would mean giving any Java process that capability.
