[arturd]

Hi I'm new in PIX and this forum so please be patience

I have a network like:


WORLD
|
(out.-X.X.X.X)
(router)
(ins.-192.168.20.1/24)
|
(out.-192.168.20.219/24)
(PIX - 501)
(ins.-10.1.1.1/24)
|
---------------------
| |
10.1.1.11/24 10.1.1.12/24
(host1) (host2)

This is a test configuration but still not working:

I can ping from host1 & host2 to pix inside int. 10.1.1.1
I can ping fron pix to host1 and host2
I can ping from pix to router gw. 192.168.20.1
I can ping from pix to World (e.g.212.77.100.101)
I can ping from router 192.168.20.1 to pix outside int. 192.168.20.219
I CAN'T PING FROM HOST1 AND HOST2 TO WORLD!! WHY!?
Why there is no connection from inside host1 & 2 even to 192.168.20.1 ?

Please help me with that!!

for the NAT [id] statement, u need another global [id] statement to take effect. So i think you miss out :

global (outside) 1 interface
(this will translate the internal ip to pix outside interface ip , which is 192.168.20.219)

also you need to add this :
access-list outside_in permit icmp any any
access-group outside_in in interface outside
(this will enable the echo-reply traffic to come back)

Thanx )
I wrote in pix:

global (outside) 1 interface
static (inside, outside) 192.168.20.0 10.1.1.0 netmask 255.255.255.0

and it works)

Once again thx!!
