Virtual Ip on Pfsense not working on Hetzner dedicated server
I have a little trouble with virtual IP, I explain myself:
I have a dedicated server at Hetzner hosting, they provide me a primary IP 95...18 / 26 So I install an ESXI with this IP address
After this I ask 1 additional IP for my pfsense, they provide me another ip 95...11 / 26, I check the separate MAC (because if I don't it's based on the MAC address of the primary IP), I configure it into my pfsense on the WAN vswitch and the LAN vswitch have 192.168.11.1 as IP, all is working fine.
I add another VM who was in my LAN vswitch who have as IP 192.168.11.10, if I let by default in DHCP, this VM can go on internet and I can make NAT to access to this VM if needed.
This VM must have his own IP address, so I ask another additional IP, they provide to me the IP 95....10 / 26, by default MAC address is the "same" as the primary IP, so I ask a separate MAC, I add this IP on my pfsense as virtual IP, I make a 1:1 NAT to my VM 192.168.11.10, I make an Outbount NAT to specify the same, so VM with IP 192.168.11.10 use as output the IP 95...10.
I made multiple times this configuration on different ISP (Serverius, Online an other) but this time it doesn't work.
I search to add the MAC provide with this IP into Pfsense but it seems not possible ?? (or I don't find how to make it)
I try to add another interface to my ESXI, add it as WAN2 in Pfsense, but when I try to add the IP 95...10 / 26 as IP for WAN2, pfsnese tell me it overlap another IP (it's normal, WAN have the IP 95...11 / 26).
I need help to make it works, is someone have an idea ?
