Two NICS / Static routing / HP-UX 11.23

[EEESEC]

Can anyone offer some assistance in setting up routing correctly on HP-UX for the
following scenario:

I have an HP-UX 11.23 system with two NICs. They are on two different networks and will
utilize different gateways. The traffic from each network needs to return through the
same interface it came in on. Destination address is known. So, I'm assuming
I will need to create some static routing entries in etc/rc.config.d/netconf similar to
this -

ROUTE_DESTINATION[0]=""
ROUTE_MASK[0]=""
ROUTE_GATEWAY[0]=""
ROUTE_COUNT[0]="1"
ROUTE_ARGS[0]=""

ROUTE_DESTINATION[1]=""
ROUTE_MASK[1]=""
ROUTE_GATEWAY[1]=""
ROUTE_COUNT[1]="1"
ROUTE_ARGS[1]=""

I would also have to remove any default route, correct?

Finally, do I need to mess with ip_strong_es_model? Should it be set to 1? Am I missing anything else?

Thanks.
