Firepower 2130 firewall rule and DHCP

Hi all,

 

Using FMC, I have configured 2x internal sub interfaces (1/14.100 and 1/14.200 which cover subnets 192.168.1.0/24 and 192.168.2.0/24 respectively) and tie them to internal zone. I have also configured an external interface 1/1 (connected to my perimeter firewall) and tied it to external zone on my cisco firepower 2130. I have created a firewall rule to allow all traffic from internal zone to external zone and verified that my client is able to access internet when its connected to either 192.168.1.0/24 or 192.168.2.0/24. I need both my internal zones to be able to access each other. I tested and found that ping between 192.168.1.0/24 and 192.168.2.0/24 works but other traffic does not seem to work. What should I do? Should I create a firewall rule to allow access where both source and destination zone is internal?

 

My cisco firepower also double up as a dhcp server. I don't find the setting for the lease time. Can anyone advise where I can find the lease time setting from the FMC GUI? TIA!
