MultiWAN with 3 pfSenses. Can LoadBalancer-Box be NAT-disabled?

[muellinger]

Hi,
i have 3 pfSense boxes in my network.

pfSense #1(Gateway7Loadbalancer) WAN -> pfSense #2 (doing PPPoE to ISP1)
                                               WAN2 -> pfSense #3 (doing PPPoE to ISP2)

pfSense #1 WAN Interface has 10.1.0.1 -> pfSense #2 LAN Interface has 10.1.0.2

WAN2 interface has 10.2.0.1 -> pfSense #3 LAN Interface has 10.2.0.2

OpenVPN Server runs on pfSense #1. pfSense #2 has a NAT + Firewall Rule to give OpenVPN to pfSense #1

To keep short. Can i put the LoadBalancer-Box into a routing only box and do all the WAN Firewall-Rules only on the two
PPPoE pfSenses? I need this to simplify rules-management.

Thanks a lot!

regards.
Carsten
