Thread: Host can't access gateway but VM can with Bridged Networking

i've set bridged networking can have kvm virtual machines accessible outside host. can access both host , vm other machines on local network, , vm can access internet host can access local network. since can access local network , same issue applies regardless of whether use host names or ip addresses suspect it's not picking gateway properly.

how go allowing vm host access internet while still having bridged networking can access vms?

i've checked far:
ping google dns (8.8.8.8 )
host: destination host unreachable
vm: suceeds

tracepath 8.8.8.8 -n
host:

code:

1:  192.168.1.15                                          0.215ms pmtu 1500   1:  192.168.1.15                                        3001.013ms !h       resume: pmtu 1500

from vm:

code:

 1:  192.168.1.1                                           7.055ms asymm  2    2:  203.109.128.90                                       59.708ms    3:  203.109.143.101                                     149.582ms  ... more

since 192.168.1.1 nat gateway vm going straight gateway , out expected, host (ip 192.168.1.15) seems not leaving box.

route -n
host:

code:

kernel ip routing table  destination     gateway         genmask         flags metric ref    use iface  192.168.1.0     0.0.0.0         255.255.255.0   u     0      0        0 br0  192.168.1.0     0.0.0.0         255.255.255.0   u     1      0        0 eth0  192.168.122.0   0.0.0.0         255.255.255.0   u     0      0        0 virbr0  169.254.0.0     0.0.0.0         255.255.0.0     u     1000   0        0 eth0  0.0.0.0         192.168.1.1     0.0.0.0         ug    0      0        0 eth0  0.0.0.0         192.168.1.1     0.0.0.0         ug    100    0        0 br0

i'm not realy sure how intepret this, me it's picked gateway properly.

/etc/network/interfaces on host follows:

code:

auto lo  iface lo inet loopback    auto eth0  iface eth0 inet dhcp    auto br0  iface br0 inet dhcp          bridge_ports eth0          bridge_stp off          bridge_fd 9  	bridge_maxwait 0

i've checked dns specified in /etc/resolve.conf correct. since things fail using ip addresses that's unlikely cause.

issues accessing things outside of subnet. can access other machines on same subnet host fine.

i encouter same problem
can not solve either
can

welcome
in advance!
