Hi!
I just set up our Astaro firewall this past weekend, but now the transparent proxy does not work over our existing SBC VPN connection. Our previous firewall worked fine, and no changes have been made to the configuration of the VPN routers.
When I set the HTTP proxy to User Authentication, users at our remote VPN site can get through to the internet, but not to all sites. Here at our local VPN site, we can browse freely. However, we are not using RADIUS servers, and no dialog box appears while browsing.
When I set the HTTP proxy to Standard mode and configure the browser to use the IP Address and Port Number, everything works fine from the remote site. But I would like to avoid configuring 100 machines.
Why doesn't Transparent proxy work from our remote site? The remote site has a different subnet address from our local site, if that makes a difference.
Example of problem: From our remote site, we can browse to the Yahoo homepage, but not to Yahoo mail or other services. From our local site, we can browse to ALL Yahoo sites.
Any ideas? Thanks for any input! I can't wait to get this firewall stable!
Thanks!
