Hello,

I am not able to connect to internet in teh spawned VM's.


Ethernet card details:

*Eth1 bridged through OVS(mybridge)              - 172.27.10.76*
*Eth3                                                            -
192.168.182.251*

after executing the command

iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE

iptables -t nat -A POSTROUTING -o mybridge -j MASQUERADE

- I see teh connectivity to VM's from my host name  ie 172.27.10.76 also
affected.

I have internet connectivity using the machine IP 172.27.10.76, but the
internet is not working in teh VM range 172.27.10.100,172,27.10.250.


I have attached the firewall log as well.

Please advise.
