ENDIAN Firewall - Strange behavior w/ DHCP & Web GUI

I just began using Endian after testing 7 other firewall distros---what a great product!

I am experiencing erratic behavior: when I finish configuring in the setup I have to renew the DHCP lease on my local machine in order to log in to the Web GUI. I have tested this from 2 different DHCP servers with the same result. Also When I log out of the WEB GUI I get a drop down window that asks me to authenticate as if I was login in. After i populate the fields with my credentials it does nothing. I have reinstalled several times and even moved it to a completely different network, but still having these issues. I have used XP & OSX clients to configure with (Firefox & Safari Browsers)

Thanks
