using a 2514 IOS 12.3. NAT seems to be working fine, but running into a problem when i try to direct traffic from my public ip to an internal private ip. Trying to do this with both http and smtp. got the proper command in config, but still not working. Every stops at the router. here is part of my config:
description connected to Internet
ip address 18.104.22.168 255.255.255.224
ip access-group 101 in
ip nat outside
description connected to EthernetLAN
ip address 192.168.0.1 255.255.255.0
ip access-group 100 in
ip nat inside
ip inspect Ethernet_1 in
ip nat inside source list 1 interface Ethernet0 overload
Maybe I am missing something myself, but I appear to be stumped on how anything is working at all. On the outside interface [Ethernet0] you have an inbound ACL applied that denies all ip packets. So any ip packets that come into Ethernet0 - whether they be reply packets on a socket initiated from the inside, or if they originated from the outside - will be denied.
It wont work because you are using NAT and PAT at the same time. With Cisco IOS, you can either use PAT or use NAT. If you want to use both, you would have to use a different IP address for each. So choose another real IP address and do your static NAT. I will suggest NATting everything and then using ACL to control what ports are allowed to the webserver and mail server.
In this case, we will have registered Public IPs available for users who are currently using private IPs. We will use one of these IP as secondary address in the ethernet port and advertise the public address obtained for the private users to the Internet. In this case, we do not use PAT. we use only NAT. Is this right?
