question about IP

[Ulkiukas0]

Hi there,
I have CISCO ASA 5520 and I'm using ASDM 6.1

so here's a problem, I have configured 2 interfaces (LAN, NET) with these IP (offcourse here they're not real, but last numbers and subnets are correct):

LAN: 192.168.5.1    255.255.255.0

NET: 123.123.123.202     255.255.255.224

I want to do one thing, I have server with IP 192.168.5.5 and how to do properly, that from outside my LAN when ppl types 123.123.123.205 it goes right to 192.168.5.5 and offcourse when server goes outside it gets 123.123.123.205

hope somebody understood what I mean and can help me?

If you're running on version 6.2 or lower, you can do static nat:

static (inside, outside) 123.123.123.205 192.168.5.5 mask 255.255.255.255

In your outside acl, you'd allow whatever traffic you want in:

access-list outside permit tcp any host 123.123.123.205 eq 80

HTH,

John

Thank You for quick answer.

But then there's again a question, how to do proper static nat?
I create one static nat rule, in original source there's my real address 192.168.5.5 and it's on LAN (inside) interface, and translated address is 123.123.123.205 is on NET (outside).
But it won't work... what I'm doing wrong?

that's it I got it,

I was trying to look from inside LAN if outside IP works, and ASA has problem with that, so everything's fine now thank You for help
