Why do PIX's specify ouside or inside for routes?

Can anyone tell me why PIX's must specify interface name to route?

PIX:

route outside 0.0.0.0 0.0.0.0 203.1.1.2 1

ROUTER:

ip route 0.0.0.0 0.0.0.0 203.1.1.2

Hi,

I'm thinking that the reason for doing so is that it makes it easier for the PIX to do Reverse Path Forwarding (RPF) checks since it will know exactly which interface each route is being sent out of.

Hope that helps - pls rate the post if it does.

You can also specify an interface instead of a gateway for a specific route in IOS. Of course, routes for directly connected networks will always be known via the interface.

To establish static routes, use the ip route command in global configuration mode. To remove static routes, use the no form of this command.

ip route prefix mask {ip-address | interface-type interface-number [ip-address]} [distance] [name] [permanent] [tag tag]
