I'm running fedora core 2 with 2.6.7 kernel when I have /proc/sys/net/ipv6/conf/all/forwarding Set on Listening Deamon's will not respond to Sync requests. if I turn it off which breaks routing of course. then the Deamons can make connections. Is this suppost to be normal behavior when the box is routeing IPv6? This only happens with ipv6 connections.
