If you want to serve http content via IPv6, then perhaps you can run httpd on your (IPv4) loopback interface, and have relayd listen on your public IPv6 interface, and forward requests over IPv4 to it ?
And then what if the HTTP request reads something like "GET [::1]" ? -- Boudewijn Dijkstra Indes - IDS B.V. +31 345 545 535
