Hello,
I have a 6509 core switch with FWSM module installed in it the outside interface of this module is connected to the inside interface
of cisco pix 506E, the outside interface of the PIX is connected to a router then to the ISP.
before writing the NATTing problem, this is the current NATTing and Static configuration for both the Module and PIX:
Module:
interface Vlan200
nameif OUTSIDE
security-level 0
ip address 10.10.10.2 255.255.255.248
interface Vlan205
nameif inside
security-level 100
ip address 172.16.205.1 255.255.255.248
static (inside,OUTSIDE) 172.16.203.0 172.16.203.0 netmask 255.255.255.0
static (inside,OUTSIDE) 172.16.204.0 172.16.204.0 netmask 255.255.255.0
static (inside,OUTSIDE) 172.16.205.0 172.16.205.0 netmask 255.255.255.0
PIX:
ip address outside 111.110.150.200 255.255.255.240
ip address inside 10.10.10.1 255.255.255.248
global (outside) 1 interface
nat (inside) 1 0.0.0.0 0.0.0.0 0 0
with this configurations all 172.16.203.0 172.16.204.0 172.16.205.0 have internet connction without any problems.
I faced the problem when i tried to change the static configurations in the Firewall module and use NAT instead of static
without changing any thing in the PIX
here what i did in the module
global (OUTSIDE) 1 10.10.10.5
nat (inside) 1 172.16.203.0 255.255.255.0
nat (inside) 1 172.16.204.0 255.255.255.0
nat (inside) 1 172.16.205.0 255.255.255.0
after making this new configurations all networks didn't have internet connections, this is my problem so anyone have a clue for this
Thanks
