from the inside to outside

so you want to send packets out then have them come back in? well.. assuming you have NAT configured you could simply ping an internet address and the packet will be returned, if you wanted the return packet to be of a specific ip address then yes firewalls like checkpoint can modify the ip of the incoming packet (and also to the outgoing packet) to whatever you choose.

If you can be more specific about what you want to do exactly then i may be able to be more help, otherwise good luck.

I do stuff like this with most of the products I work with though, if I get your question.

There are some firewalls for which this is not possible, as the firewall will recognize the incoming packets and discard them.

There are some firewalls for which this can be done provided that the packets are reflected off of an outside device.

With Cisco IOS-based routers with "Advanced Security" or "Firewall Feature Set", you can handle it inside the device by carefully using "loopback interfaces" and selective routing.

I have no information on the capabilities of other major brands.

Huh? Any proper firewall configuration will recognize the incoming traffic being related to the outgoing requests and allow it.

Thanks to all for the responses, and I am sorry for my vagueness.
