NAT between lans

hsoares

Hello.

Is it possible to NAT between lans in pfsense ? Here's the problem:

PFS1 LAN 1: 192.168.11.0/24
PFS1 LAN 2: 172.16.1.1/30

PFS2 LAN 1: 192.168.16.1/28
PFS2 LAN 2: 172.16.1.2/30
PFS2 LAN 3: 172.16.1.5/30

PFS3 LAN1: 192.168.12.0/24
PFS3 LAN2: 172.16.1.6/30

So I have 3 pfsense boxes serving clients on LAN1 subnets with back to back networks between them for routing, I want to NAT requests from PFS1 LAN1 subnet has they reach PFS2 and going to PFS3:

192.168.11.1 accessing 192.168.12.1 routes trough 172.16.1.2, applies NAT has 182.168.16.2, routes trough 172.16.1.6 and reaches 192.168.12.1 has 192.168.16.2 so the packet has a route back, which can only be on 192.168.16.0/28.

Is this possible ?

I have all the routing taking place and connections from 192.168.11.0/24 reach PFS3 with destination 192.168.12.1, but the source IP is not being nated and appears has 192.168.11.1 instead of 192.168.16.2.

On PFS2 box I have enabled advanced NAT and created a rule like this:

Interface: LAN2
Source: 192.168.11.0/24
Destination: 192.168.12.0/24
Nat Address: 192.168.16.2/32
ANY dst and src port

But the packets are still hitting destination with the original src address .

Any way of making this work ?

Thanks.

Huh… why'd you do any such thing?

Cause the costumer only routes 192.168.16.0/28, politics.

Nervermind I get it. I was doing the NAT at the wrong interface, working now.
