 |
|
Hi,
i am unable to configure native ipv6 on a kvm guest. Does someone have a suggestion or more info?
Should i post ipv4 addr and route too because it must be a routed setup?
host:
/etc/conf.d/net
| Code: | config_eth0=( "192.168.98.66/27" "coff:eeba:be61:1261:1261::2/59" )

brctl_br0=( "setfd 0" "sethello 0" "stp off" )
config_br0=( "192.168.212.241/29" "coff:eeba:be61:1261:ff::1/59" )
config_qtap242=( "null" )
tuntap_qtap242="tap"
tunctl_qtap242="-u root"
routes_qtap242=("192.168.212.242/32 dev br0" "coff:eeba:be61:1261:ff::242/128 dev br0") |

| Do you have ipv4 working in the guest? From the configuration you pasted, I would be a bit surprised if you have a working network at all. You create a bridge device, give it an address, but do not put any devices in it. What devices are you trying to bridge together? |

hi,
subnet is routed directly to main ip, Because of a MAC filter i need a own gateway (88.198.212.241/29 on br0).
with
#bridge_br0="eth0 qtap242 qtap246"
server is unrachable via ipv6. thats why a want routed config on ipv6 too.
# ip -4 a

Hi,
Now it works. here is
/etc/conf.d/net
| Code: | depend_br0() {
need net.eth0 net.qtap242
}
config_eth0=( "null" )
bridge_br0="eth0 qtap242"
#rc_need_br0="net.qtap242"
brctl_br0=( "setfd 0" "sethello 0" "stp off" )
config_br0=( "192.168.98.66/27" "coff:eeba:be:1261::2/59" "192.168.212.241/29" "coff:eeba:be:1261:ff::1/120" )
routes_br0=( "default via 192.168.98.65" "default via coff:eeba:be:1260::1")
config_qtap242=( "null" )
tuntap_qtap242="tap"
tunctl_qtap242="-u root"
routes_qtap242=("192.168.212.242/29 dev br0" "coff:eeba:be:1261:ff::42/120 dev br0")
