FWIW I used to run a quite large LDAP directory behind F5 LTM's. It isn't uncommon for apps to leave idle connections for many hours and then expect them to be up and running instantly still... 2 hours may be too short.
However there is a chance that either the client or the server will be specifying SO_KEEPALIVE on the sockets. If so, then setting the tcp keep interval to something reasonably short (Defined as about 2/3's of the minimum idle timeout value of all the devices in the solution) will mean that the IP stack itself will send keepalives (Basically it'll send ACK packets now and again so the endpoint, and any firewall/stateful devices in the path know the endpoints havent 'gone away').
