Hi, In advanced zone you can use openVswitch. Please share setup details like hypervisor, public ip range.
Did you deploy vm with default network offering ? Please share your below commands output on router via pastebin.com Iptables -L -nv Iptables -t nat -L -nv Iptables -t mangle -L -nv Ifconfig Lets figure out is there any problem in cloudstack configuration.
