SUBNET NAT

[Math43]

Hello,

I've got the following network (simplified, i've got many more networks of right side)

172.18.3.0/24<----->.150 vmx0[OPNSENSE BOX]vmx8_vlan2595 .150<---->192.168.151.0/24

I'm trying to nat the whole 192.168.151.0/24 to another subnet (10.155.0.0/24) because i'm not able to readdress this network.

I need to setup
- a source nat to replace source IP vmx8_vlan2595 ip
- a destination nat to translate 10.155.0.0/24 destination ip to real 192.168.151.0/24 ip.

rules extract from pfctl
nat on vmx8_vlan2595 inet from any to 10.155.0.0/24 -> 192.168.151.150 port 1024:65535
rdr pass log on vmx0 inet from any to 10.155.0.0/24 -> 192.168.151.0/24

For now it's not working. Same configuration is working on Sophos firewall
