ICMP drooped After applying NAT between sub interfaces

Hello , I am trying to connect ASA firewall to a switch as firewall on stick 

 

pc1 (Vlan 10) ---------

                                       switch     ----------- ASA

pc2 (Vlan 20 ) ---------

 

int g0/0
no ip add
int g0/0.10
vlan 10
ip add 10.10.10.1 255.255.255.240
nameif Inside_1
security 100
no shut
int g0/0.20
vlan 20
ip add 10.10.10.17 255.255.255.240
nameif Inside_2
security 100
no shut

 

this is my configuration when i try to ping PC1 to 2 or vise versa its works

but the issue that ( i want pc2 to see PC1 as 7.7.7.7)

 

#Object for PC1_NAT
Object network Ip_7
host 7.7.7.7

exit

nat (Inside_1,Inside_2) source static Ip_PC1 Ip_7

 

the ping fail PC1 send request to 2 , PC 2 replay to 7.7.7.7 then packet is droped only from PC2 side

i tried to ping PC1 from PC2 as ping 7.7.7.7 only request send to gateway

Re: ICMP drooped After applying NAT between sub interfaces

I have solved it thanks there was another Nat statement above 

 


nat (any,outside) source dynamic any interface

 

just changed the orders.
