Hi, after I have set up radvd on my OpenWrt kamikaze 8.09 router yesterday, I was able to obtain IPv6 address from prefix on Windows XP, however my Linux computer with OpenSuse 11.0 refused to retrieve the address from router advertisement. I have restarted the network service several times, tried to disable the firewall but with no results. Much fine-tuning of radvd and captured packets with tcpdump/wireshark/radvdump, searching the forums and googling I was preparing to throw in the towel and configure the address manually. When I was last checking the sysconfig files, I found by accident that IPV6_FORWARD option in sysctl configuration was set to yes for some reason. When I disabled it and the net.ipv6.conf.all.forwarding (by setting it to 0) on the client, the address was finally retrieved. Does anyone know, if the linux kernel (2.6.26.20 x64 in this case) disables IPv6 autoconfiguration from router advertisements when in IPv6 forwarding mode, or whether this is default behaviour in such situations?
