Creating static NAT blocks outbound traffic Cisco ASA
- by natediggs
Hi Everyone,
I have two web servers sitting behind a Cisco ASA 5505, which I don't have much experience with.
I'm trying to create two static NATs. One static NAT that goes to xx.xx.xx.150 and another that goes to xx.xx.xx.151. I've created the static NAT for the .150 web server and it works FINE. Incoming and outgoing traffic work great. This is the staging web server. I now need to duplicate the setup for the production web server.
So, I connect the webserver to the firewall, change the public IP address on one of the NICs reboot the server and I have outbound internet access. Then I run the command:
static (inside,outside) xx.xx.xx.150 192.168.1.x which is successful.
I then run the command:
access-list acl-outside permit tcp any host xx.xx.xx.150 eq 80
Which is successful.
I then try to browse the internet and I get nothing. I try to telnet in through port 80 and I get nothing (though I'm guessing because the response to the telnet request is being blocked).
I've tried this with the production web server and then I tried it with another web server that is for internal testing and have the exact same problem. Both work fine until I run the static NAT rule and then no outbound internet access.
I have a feeling that it's something simple that I'm missing, but my limited experience with this device is killing me.
Below I've pasted the current configuration. I'm currently trying to get this to work on the .153 server which is the internal testing server. Once I can verify that works, I'll try it with production.
