I work for a fairly large company and I am finding that our main IP in our class 3 public IP block that we use for NAT/PAT for all our internet access is denied from the USPS.com web site. For testing, I sourced from another server that uses a different IP from our public black and I was able to connect with no problems, which tells me this is not an issue with our firewall, but an issue with being denied access by USPS.com. I need to find out who to contact to be able to assist with this issue.
