Issue Description
In Egypt, customer use the 200E with a simple config, allow all zones and a nat application,but it cause a big slowness for their network, they are very upset and tell us when they use cisco firewall there is no such trouble.
Alarm Information
We ues ping test, see 80% packet loss in the network, but our firewall cpu and memory are in good health.
Handling Process
Change our nat config to nat pool, the speed is normal now.
Root Cause
See the nat config.
interface Vlanif1
alias Inside VLAN
ip address 10.1.1.2 255.255.255.0
#
interface Vlanif15
alias Outside VLAN
ip address 192.168.15.2 255.255.255.0
nat enable
detect ftp 

Compare with the cisco nat config,we find cisco nat is using nat pool, while we use nat interface.
Suggestions
If our device is working well, but the internet run slowly, it is often because of the internet environment, the site slowness is just because one ip speed is limited by other device in the system, when we use nat pool for many ip, problem solved.
