MS Proxy 2.0 & Secure Pages .

By husam ·
Whenever I’m trying to access a secure page on any site I get this message:

ICMP network is unreachable

As far as I have been told , MS Proxy 2.0 Does not support ICMP, but there is no work around that enables me to access these securesites, we have purchased huge licenses for this proxy.

Check out the following Q article from www.microsoft.com/technet. Q170292.

Hopefully the explanation of what ICMP is and the error codes will help you out.

It seem like you enable control access to certain protocols and sockets. If you disable the control access of the winsocks, it will go away but leave your clients to have full permission for the web. to work around that, enable the outbound and inbound of the icmp ports to the one that the website is using. ex) protocol ICMP port 1405 inbound 1208 outbound. Please note that messing with this is like messing with the registry of your server. but won't be as bad.

ICMP itself is just a transport protocol for TCP/IP. M$ always bad with terms they are using for error messages. :)

Seems to me, your current proxy configuration prevents to work with HTTPS, which required to open incomming tcp port 443. If you have any questions, feel free to e-mail me.

Make sure that users have the necessary permissions to use HTTPS. This can be found in the properties for either the Web Proxy or the Winsock Proxy (whichever you use) in MMC. Also, if you use packet filtering, make sure dynamic packet filtering is turned on, or the proxy server will deny itself access to the necessary ports. If you have enabled packet filtering and dynamic packet filtering and still have problems, establish a filter for TCP port 443 that permits all internal hosts to send outoing traffic to all outside hosts.

The problem is not a problem of too much buffer space, it's a problem of too LITTLE buffer space. What happens is that when large amounts of data are stored in the buffer, the software (since it doesn't bother to check the lenght of the data) writesright past the end of the buffer and into other data, and possibly executable code. If such executable code is overwritten by malicious code sent to the buffer, the malicious code will be executed with whatever permissions are held by the host process; in the case of a system service, those permissions are quite liberal.
