User Login

[shaggy]

I have created a user login form on my main http://www.domain.tld (public) site posting to admin.domain.tld(ispcp site) the form and system works fine however I get Error 310 (net::ERR_TOO_MANY_REDIRECTS): There were too many redirects. when I use it to login I then click in the address bar and hit enter and it show the page with Request from foreign host was blocked! echo'd many times on the main page, is there anyway I can stop this? I want to enable my users to login from the main page.
