I'm trying to access a website (management console of another firewalls sonicwall) over the internet e.g. https://x.x.x.x but it gives me an error. Port on website is the standard: 443.

Error:
Network Access Message: The page cannot be displayed
Technical Information (for Support personnel)
Error Code: 502 Proxy Error. Connection refused(10061)
IP address: x.x.x.x
Server: isa2004
Source: proxy

Normally I get a security window (certificate), click on ok and I see the website where I can fill in usern./password.  I'm able to access these websites via another firewall, it means that the isa2004 is blocking this.
Homebanking via https is working.

In the ISA2004 monitoring logging I see:
SSL-tunnel x.x.x.x 443 Failed Connection Attempt Allowed ports outbound

Setup:
-ISA Server2004 Edge firewall SP2
- Rules name "Allowed ports outbound" = allow https int. ext. all users
-Client =  webproxy

It's possible that ISA is blocking it - conversely, it is also possible that the remote Sonicwall doesn't allow managemnt connections from ISA's IP address. You did receive a "Connection Refused" message indicating that ISA reached the destination host, but that host would not allow a connection.

ClintD, you were right the problem was the other firewall, it only allowed remote management from a specific network range.  Thx.

Hi guys,

I have the same error but different scenario. I published my webmail to the internet (https) and itīs working normally for users who access from internet. But when Iīm in internal network, I just canīt access the webmail server using the external address. Itīs giving me the same error:

Network Access Message: The page cannot be displayed
Technical Information (for Support personnel)
    Error Code: 502 Proxy Error. Connection refused(10061) IP Address: x.x.x.x Date: 22/2/2008 18:33:10 [GMT] Server: servername.domain Source: proxy
I already created an access rule allowing localhost from localhost, but didnīt work out! What am I doing wrong?

Iīm currently using ISA2006 and exchange2003.

Hello Sadiq, thanks for the help.

But if I use no proxy in the SECURE field, Iīm not able to access any page who the content is https (port 443). My problem is that Iīm trying to access my own webmail using the external address, but I canīt!
