Please let me start by saying I am a newbie. I apologize in advance for stupid questions.
My problem is this. I have setup static and conduit statements in my pix to access an internal web server. I am using the same format as is used for other boxes (ftp and www) that are accessed from outside the network. These work fine but I can't access my new web box.
I did a little bit of troubleshooting and it looks like packets are getting past my router but timing out when it gets to the pix.
In my logs I am getting the following error:
Deny inbound (No xlate) tcp src outside:61.94.56.23/80 dst outside:216.191.146.83/2796
I wasn't sure why it was trying to come through on /2796. Also important to note here is the address 216.191.14.83 is the IP for my global (outside). It is not the IP address that I am trying to reach, which is 216.191.220.147/
Any ideas on where I can begin to troubleshoot this problem?
Thanks in advance.

Hi,
Please share the configs (change/hide the IP addresses).
The log message that you are referring may not be related to your issue.
Thanks

Ok thank you. Here it is. I hope I haven't hidden the IPs so much that you can't make sense of it. Please let me know.
Thanks.

Hi,
My bet, hiding the IPs are making it more difficult to conclude, please send the config unicast to nkhawaja@cisco.com

the debug doesn't indicate much, as it could be an attack from the internet.
would you mind posting the config
02-17-2004 03:33 PM
firstly there is bug with 6.3(1) regarding to nat, i would suggest you to upgrade the os
secondly do a sh xlate and check whether or not there is an entry for the new server

Thanks!
