@phil.davis:
I think this would work. Add 6 rules, 2 on each inside LAN, to force traffic for the 2 other "local" outside subnets to the gateway you want.
Here are the 2 rules for WLAN_inside:
On WLAN_inside, pass all protocols, source 10.200.115.0/24, destination 130.225.127.0/24 and in Advanced Features, Gateway, select the WLAN_outside gateway address.
On WLAN_inside, pass all protocols, source 10.200.115.0/24, destination 192.38.116.0/25 and in Advanced Features, Gateway, select the WLAN_outside gateway address.
Excellent idea - and it even works :)
Thanks.
