You can. However, the addresses you use in each context need to be different. In that way, when the packet returns to the firewall, the firewall can distinguish them to appropriate context. If you want to use same IP address as well, you might want to use different MAC addresses in each context.

The document above explains this scenario.

Hope this helps.
