["Daniel Tyrode" <dtyrode4@xxxxxxxxxxx>]

Hi again,

I have done some tests with radvd, downloading the original files, compiling
and running. It seems that my problem is not related to radvd. Is it
possible on Usagi's Stable Kit 5.0 to support IPv6 forwarding (sysctl -w
net/ipv6/conf/all/forwarding=1) and stateless configuration   (sysctl -w
net/ipv6/conf/all/accept_ra=1 ) at the same time ? ... everytime I turn on
the IPv6 forwarding my NIC no longer sends Router Solicitations. However
this does not happen with SuSE's native kernel 2.4.21-215-default ( I can
run sysctl -w net/ipv6/conf/all/forwarding=1 and yet send Router
Solicitations and update routing tables). Is there a kernel option I should
be aware of ?

Thanks in advance for your help,

Daniel

Hi,

I am trying to run IPv6forwarding on a linux box with the following
characteristics:

* SuSE 9.0 ( kernel 2.4.21-215-default )
* Usagi's stable kit Release 5 ( recompiled the kernel 2.4.21 )
* IPSec functionality configured and running as described in Usagi's Howto

The IP address allocation is through radvd ( v 0.7.2 ). I can succesfully
activate IPv6forwarding ( sysctl -w net/ipv6/conf/all/forwarding=1 ), yet
when I do so the default route vanishes. If I set the default route
statically I recover connectivity, but no further Router Adv. will change
this status. I understand that this happened in previous releases of radvd,
yet the funny thing is that when I reboot the machine and start with SuSE's
default 2.4.21-215 kernel, I can activate IPv6Forwarding without loosing my
default route.

For some reason I also get 2 Site-IPv6 addresses assigned, one is always the
same ( prefix + token ) yet the other one changes constantly. This does not
happen when I run SuSE's default kernel. I have tried to compile the radvd
that comes with the Usagi kit, but I get an error:

gram.y:316.13: parse error, unexpected ":", expecting ";" or "|"
make: *** [gram.c] Error 1


Any ideas, suggestions ??

Thanks in advance,

Daniel
