I am facing a problem for my dialin clients. We are providing them dialin facility to our office network to access internet through our office lease line, so in this regards we installed Microsoft ISA Proxy Server and given them permissions to access internet with the facilities of browsing internet, accessing realaudio, realvideo, icq, msn, etc. We enable the SecureNAT feature of Microsoft ISA Proxy in order to get all of these facilities but the problem is accept browse internet they can't do any thing. We don't want to installed firewall client (Proxy Client) for them as some times there are dialing to our local ISP.
The dialup clients are using windows 2000 professional.
Access Server is 3620 Router.
Authentication server is ACS 2.6 TACACS+
Proxy is Mircosoft ISA Proxy Server.
Any help will be highly appreciated.
