Hi,

it is clear that you have an access rule blocking the web site. Check ISA real-time logs to see what access rule is denying the access.

Hi,
This's one of problem that is not easy to result, but first you can go and check with your browser for proxy connection,you can go to Configuration-->Networks-->Properties your Internal Lan -->check Web Proxy, Check Web Browser configuration, you can add Bypass proxy for Web Server (url)etc...

For real-time logs go to Monitoring select Logging Tab and click Start Query, from now you can start your download and looking the result from isa, see what access rule is denying the access.

Ong

Hi,

are you downloading using HTTP protocol?
quote:

Source: Internal ( ***.***.**.**:1202)
Destination: External ( **.**.**.**:3478)
Protocol: Unidentified IP Traffic (UDP:3478)

The rule denying the acces is the Default Rule
quote:

Rule ClientIp clientusername Sourcenet DestinationNet HTTPmet Url
defaul Rule ** ********** Internal External GET ****

It means, no other rule matched the request.

Regards,
Paulo Oliveira.
