How to find out the address after the broadcast?

Question

Cisco

There are 2 interfaces on the router: fa0 / 0 - Internet fa0 / 1 local.
In the outgoing direction, fa0/0 has an extended acl that allows traffic out for certain ports.
It is necessary that all ports be open for some local ip. Addresses at the exit from fa0 / 0 after translation (instead of local we see the address of the external interface). How can I find out the local address after broadcasting?

Answer 1

sh ip nat trans

Answer 2

did not try to hang up this acl on fa0/1 in? there he belongs, so as not to load the cat with unnecessary broadcasts, which will then be dropped by the rule. At the same time, your task will be solved :)
