2 Wan ip translation error to LAN

hello

very easy config, I get 2 WAN IP on 2 ether ports via DHCP
176.X.X.10/24
176.X.X.15/24

GW for both is 176.X.X.1

I have 2 lan, 192.168.0.0/24 192.168.1.0/24

I set

Src-nat source 192.168.0.0/24 src-nat 176.X.X.10/24
Src-nat source 192.168.1.0/24 src-nat 176.X.X.15/24

so 0.0 lan should have wan ip of x.x.x.10, and 1.0 lan should have x.x.x.15.

But, when I enable one of the WAN links, internet connection is lost. on only one WAN link, it works as it should

whats problem with 2 wans simultaneously? (this 2 WAN links are connected then to 1 switch)

Can you post your actual NAT rule? It should work fine assuming your provider allows you to have two addresses.
