My Linux router is one end of an ipv6-in-ipv4 tunnel. On my home lan I have a /48 subnet. If I go out from a station in the lan then its ethernet interface's global address is used as it should be. If I go out from the router machine then the ip address of the tunnel's local endpoint is used as source. So far so good, that's the correct behavior according to my routes. But now I want to set a route on the router machine to a specific subnet in the internet, and the machine should use the global address from its ethernet interface to show that it's a part of my lan. Unfortunatly the command ip -6 ro add <destination subnet> dev sixxs src <my eth0 address> is accepted but the source address is not used. An ip -6 ro ls Doesn't show the outgoing address either. Do I need a newer iproute utility, did I make a mistake or is this a linux bug? I use Debian's version of kernel 2.4.18. Regards Holger
