HTTP through VPN - 14.Dec.2004 6:00:00 PM

I've set up a site-site dedicated VPN connection with internal addresses in the 192.168.13.0/24 range. Our internal network uses 10.0.10.0/24 addresses. We have some development sites that resolve to our dev.company.local (ie client.dev.company.local) on 192.168.13.12 (for example). When i try to access client.dev.acumium.local, ISA server is taking that request and turning it into http://192.168.13.12 which doesn't work. Any internal sites in the 10.0.10.x range work fine. I have a "route" relationship setup between the internal (10.0.10.0) network and the site-site vpn network. There are several sites running out on the remote network that we need to access. Some on different IP addresses (same 192.168 range), some will also need certificates installed (which i haven't even gotten to yet). Can anyone explain what the proper configuration would be to allow these URL's to pass through ISA unchanged? I'm testing with a firewall client installed on my workstation, but fellow office workers without the client also have the same problem.

Thanks,

Jason

I should add that we also have development sites on the 10.0.10.x network that use the client.dev.company.local naming scheme.

I did come across another article that stated the same scenario and problem. In order to get it to work, I had to disable the Web Proxy Filter for the HTTP protocol. WHY? So I assume this means no filtering at all. How can I get this to work and retain the HTTP filtering capabilities?

I have a problem similar to this. when 2 sites are connected through a vpn (site to site) ISA2004 to a PIX firewall. I can connect to a web site from on side of the vpn to the other with http filtering enable.If an iis server has a redirection to another site instead of a plain website iis will just timeout. This behavior it present only if http filtering is enable on the http protocol

Thanks for your help.
