Multiple WAN-adresses, Gateway in same network - how to setup?

[hebein]

Hello,
from my provider I got the following IP-Adresses

78.X.X.74-78
subnet 78.X.X.72/29
GW 78.X.X.73

When I try to set up my Netgate-router, pfsense says, that it cannot create the gateway, as the gateway is in the same network as my IP-adresses. How can I setup the network correctly?

Regards,
Gunther

use one IP address as WAN IP address for example 78.X.X.74/29 and GW 78.X.X.73
and assign other IPs as VIP on wan interface
