Pix 506 Configuration

Unanswered Question
Nov 12th, 2007

I have a Pix 506 that I'm trying to intergrated as a perimeter firewall.

I've looked over the config and see no issues yet I can never get any inbound web services to function off of any of the static NAT statements.

Both outside and inside interfaces go up/up and run clean - although the outside interface does attach to a hub at 10 / half.

Can you access the internet from inside? Also, where are you trying to access the outside IPs from? Are you plugged into the hub in front of the firewall or are you on the inside network trying to access via the public IPs?

Thanks,

Brandon

Internal access to the web wouldn't work b/c DNS would fail when I would integrate this firewall. It would instantly start working when I try the original firewall that his one is replacing.

External access was attemped from another Internet connection - not the hub.

Can you ping the external IPs from the Internet when the PIX is plugged in? They are the same IPs as on the old firewall correct?

The external IPs aren't pingable and they match exactly the previous firewall's IPs.

I was wondering if it might be the ARP cache on the edge router sitting in front of the firewall. I did ping from the firewall to the inside interface of the edge router successfully.
