I have a cisco 3640 router and a cisco pix firewall 515 running 6.3 ios. I am not able to access some website like www.verisign.com..., but when i give any public proxy server at my IE settings then these websites are working. We had web marshal(URL Filter) before and all IE requests go through that and now we have removed the web marshal and the configuration on the firewall related to the filter url for web marshal has been removed. What could be the problem and how can rectify the same.
