hello every one
i am setting up a FE& BE Exchange topology on my network.
The Scenario is as following
1- i have my front end exchange on DMZ area and back end exchange on Protected lan
2- i have ASA5540 as my firewall
3- Natting is implied on the 3 of ASA5540 interfaces (outside,dmz and lan)
4- i need to secure connection using (IPSec tunnel ) between the Fe/Be exchange through ASA5540
how would i do that?
NB: moving the Front end exchange to protected lan is none an option
