We are having a strange problem that is only affecting the company owners home network. I will try to be as descriptive as possible. Our office has a single T1 coming in from our ISP from there it goes into our PIX 515e. After the PIX is a Cisco 3750 switch. The owner has a single fractional T1 running to his house, this is a point-to-point from the office only. On the house end there is a cisco 1750 router and on the office end we are using a cisco 2821. Now the owner just a got a new DirectTV system and needs to use the supplied wireless bridge to connect to his network, this is working with no issues. The problem comes in when internet is involved. We use a barracuda webfilter setup in proxy mode. the owner's pc at home cannot browse the web without the proxy being entered into the settings. Any other PC like mine in the office can bypass the proxy using the PIX as the default gate way. I have looked at all of hte rules i can think of that may be blocking http traffic from his house to the office and so far have had no luck. For security reasons we have icmp disabled making it hard to trouble shoot since i am never able to ping google.com for testing no matter how i am connected to the network. I am not sure whether to take this up with cisco or with Barracuda to have the resolution. I think it something in our cisco stack that causing the troubles but am unable to find the root cause. I have checked all of the IP routes and everything looks fine. As i mention i can use the web on my computer at my desk without having any of the proxy settings in place.
