Cant ping through firewall cisco

[quoc anh]

I have my firewall like this:

int gig1/1

nameif inside

ip add 192.168.100.1 255.255.255.0 (switch 0)

no shut

int gig1/2

nameif outside

ip add 200.100.10.1 255.255.255.252 (switch 1)

no shut

int gig1/3

nameif DMZ

security-level 50

ip add 192.168.200.1 255.255.255.0

I've already configured route to outside

route outside 0.0.0.0 0.0.0.0 200.100.10.2

router rip

ver 2

no au

net 192.168.100.0

The problem is I cant ping from pc0, (inside 192.168.100.2) to pc5, (outside 200.100.10.2) 

Please help me !!

You need to make secuirty level for Inside to be 100

And also ypu need icmp inspection under policy map

You will also need an ACL that explicitly permits the ICMP echo-reply return from the lower security interface to the higher security interface.
