Hi I use FlatDHCP network and I create two provate network which is 10.0.0.0/24and 10.0.1.0/24 I launched a instance and give him a public ip address, but can't ping to it, (it is very odd that I can mtr it) after debug I find that the vm's default gateway is set to 10.0.1.1, and on host only have a SNAT of 10.0.0.0 after change gateway, it start to work, my question is that, does the SNAT of 10.0.0.0 is hard coded? or other way to solve my problem(use two private network) Thanks in advance Best Regards -- =========================== William Herry WilliamHerryChina at Gmail.com -------------- next part -------------- An HTML attachment was scrubbed...
