OpenBSD & IP Forwarding & IP Failover
Hello,
It's nice to find a forum about BSD, I hope I will find a solution to my problem... First, sorry for my english. I have a dedicated server with ESX 5 running. 1 Public IP, for the ESX. I have install, for testing, two virtual OpenBSD The first one, with 2 networks interfaces. The second with only one network interface The goal is to run the first BSD as a FW with IP Forwarding. It as 2 networks interfaces, em0 ---> IP Failover with virtual Mac address relied to internet em1 ---> Local network 192.168.1.1 The second BSD em0 ---> 192.168.1.2 As you can imagine, i want to add several server connected to a local network with a internet connection through the FW OpenBSD with the 2 networks interface.. I already did that, but with real physical server, and it was working well. Now, with virtual server it do not work My first problem was to configure on the FW a gateway that is different from the IP Failover subnet. But i finally did it like that : route add -host <<IP_gateway>> -link em0 -iface route add default -ifa <<Failover_IP>> <<IP_gateway>> And it work, I can ping any internet IP from the FW I configure the em1 with 192.168.1.1 I activate ipv4 forwarding in sysctl.conf I had translation rules into pf.conf and pass all simple rules. From the second BSD server, which has only one interface 192.168.1.2, I can ping the em1 interface from the FW (192.168.1.1) But I can't access to internet It seems the IP Forwarding doesn't work. Is it because on the FW the default gateway is not in the same subnet than the em0 IP address ? If someone had any idea about what is happening here ? Sorry if i'm not clear, I you need more information, just ask ! Thanks ! |
