I'm trying for 3 weeks getting my configuration running, without any success. I hope anyone of you guys can help me.
My problem is to get running additional ip adresses, so my plan is to give every virtual machine a different ip address (OVH Failover IP)

My Equipment:

ISP: OVH
Hypervisor: ESXi 6.0
Hypervisor IP: 32.37.68.58

WAN

• IPv4 Configuration Type: Static

• IPv4 Address: 5.196.111.243

• IPv4 Upstream Gateway: 32.37.68.254 /24

LAN

• IPv4 Configuration Type: Static

• IPv4 Address:172.16.0.1 /24

• IPv4 Upstream Gateway: None

WAN2

• IPv4 Configuration Type: Static

• IPv4 Address: 193.42.21.183

• IPv4 Upstream Gateway: 193.42.21.254 /24 (1.) Is this correct? I have choosen this because I can't select the same upstream gateway from WAN1)

LAN2

• IPv4 Configuration Type: Static

• IPv4 Address:172.16.2.1 /24

• IPv4 Upstream Gateway: None

pfsense -> Gateways Settings:

GW_WAN 32.37.68.254        32.37.68.254 Online
GW_WAN2 193.42.21.254    193.42.21.254 Offline (2.) Why this one is colored offline?)

#1 Firewall Rule:

Action: Pass
Interface: WAN2
Address Family: IPv4
Protocol: TCP
Source: Any
Destination: Single host or alias -> 193.42.21.183
Destination Port Range: from: SSH(22) to: SSH(22)

#2 Firewall Rule:

Action: Pass
Interface: LAN2
Address Family: IPv4
Protocol: any
Source: LAN2 net
Destination: any
Advanced Options: Gateway: GW_WAN2 193.42.21.254

I want to SSH to a VM in 172.16.2.2 (which is in the LAN2)
It looks like, the traffic goes to 172.16.2.2, but the pfsense can't send it to the source address.

What I have tried and worked is the following rule:

#3 Firewall Rule:

Action: Pass
Interface: WAN2
Address Family: IPv4
Protocol: TCP
Source: any
Destination: Single host or alias -> 193.42.21.183
Destination Port Range: from: HTTPS(443) to: HTTPS(443)

With this rule, I am able to get a webpage (pfsense login, thats not what I want, but here I can see that anything happened in the background).

I am really frustrated wasting so much time without any solution. Did I have to uses outbound NAT or something? What is my problem? :(
Thank you so much for reading this!
