I bet there are hundreds of people in that companies who would certainly
bring much more benefit if they played WoW.

Did I respond to this?

2nd-life is the contrapositive of what I look for in a virtual world. I
want to escape to a fantasy world that's different from the real world.
2nd-lifers seems like a copy of this world where you have more control
and influence.

I'd rather be a toon in World of Warcraft:-)

Hi,

I just want to allow flows from Outside to Inside on Pix ver 6.3. I'm
totally confused since it doesn't allow me to perform the operation. Please
check the configs below and guide me if its wrong.

interface inside securtiy level 100
interface outside securtiy level 60

access-list out2in permit tcp 1.0.0.0 255.0.0.0 10.0.0.0 255.0.0.0
access-group out2in in interface inside

nat(inside) 0 access-list out2in outside ----> is that outside required n
tell me y it is used?

And further should i need to apply this to my Outside interface or inside
interface. i want the addresses to be sent as such without Natting to my
internal network.

well, actually, according to the cisco jargon at
http://www.cisco.com/en/US/docs/security/asa/asa72/command/reference/s8_72.html#wp1202525

these are BOTH "static nat" - the 2nd one is regular old
static nat and the 1st, with the access-list, is called "policy nat".
to qualify for the term "static pat" you would need the extra "tcp" or "udp"
keyword just after the (inside,outside).

[snip - they are both the same type so I think the nat precedence
rules you listed
are not too relevant]

I still say the statements seem non-conflicting, because the "mapped_ip"
[the IP address right after the (inside,outside)] is different. Reading
the Cisco docs, my understanding is that if a packet comes into the PIX
with a ip.destination of "mapped_ip" (or in the "mapped_ip" subnet)
then the pix translates that ip.destination
to what the "static" command tells it to - namely the "real_ip" in
regular static nat.

in sivakumar's example. the mapped_ip is 1.1.1.2 in the 1st static,
and 10.0.0.0 in the 2nd, so there is no conflict. Am I wrong?

However, I am confused about one thing in the policy nat. here is the exaple:

access-list rule1 permit tcp 10.0.0.0 255.0.0.0 host 1.1.1.1
static(inside,ouside) 1.1.1.2 access-list rule1 0 0

instead of just a real_ip subnet (as in the regular static),
the access-list in fact
has a subnet in the source field (10.0.0.0/8) and ANOTHER subnet in the
destination field (1.1.1.1/32)... so when a packet comes into the PIX
with ip.dest=1.1.1.2, how is it translated? using the source (10.0.0.0) or
the destination (1.1.1.1) in the ACL?

moreover, let's assume that the translate-to ip is the ACL's destination
(1.1.1.1 in this example) - what does the OTHER (source)
field do?

Can any PIX mavens out there shed some light?

PIXes are so weird.
