Natting Help

[admin_2]

Hi,

I have Cisco 515E , I have not applied natting .

My problem is i have one software which I need to connect to some different location.To connect to that software I've to use static command , which interprets any internal IP going out as external(public IP), I cant waste my Public IP . I wanna know how to go about it.

Thanks,

Hello Raghu,

Try using port address translation (PAT) translating on port numbers that your application uses.

Below are links with information on NAT and PAT:

Hi Raghavendra,

Here are the steps for PIX software versions 5.0.1 and later using ACLs.

1) Define a static address translation for the inside web server to an outside/global address.

static (inside, outside) 175.1.1.254 10.200.1.254

2) Define which hosts can connect on which ports to our web/FTP server.

access-list 101 permit tcp any host 175.1.1.254 eq www

access-list 101 permit tcp host 199.199.199.24 host 175.1.1.254 eq ftp

3) Apply the ACL to the outside interface.

access-group 101 in interface outside
