Hi, I am currently in the process of migrating some of my machines to a different ISP and I have some difficulties.
My zones are configured with one NIC (net0) in our internal network and one NIC (net1) on the public network. The default gateway is currently on net1. I received a new range of IP addresses (in a different subnet that the previous ones) from my new ISP. I would like to add a new NIC (net2) and switch the default gateway to net2. Up to this part everything is fine. The issue is that I would like my zones to be reachable on both net1 and net2 but as soon as the default gateway is changed from net1 to net2, the zones are not reachable on net1 any more. After some reading on multihoming, I noticed that routing is solely based on the destination IP address and not the source. It means that my zones are probably answering to the traffic on net1 through net2 and my ISP might be blocking asymmetrical traffic. I also found that source address dependent routing might be the solution. I found this https://docs.oracle.com/cd/E36784_01/html/E37475/gnkme.html but I don't know if it related to my issue or not. Does anybody has any information or documentation on this kind of setup ? ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
