I have 2 SR520's with a hardware VPN established. I have Windows XP Machines that work great in this setup, however, Windows 7 Machines aren't able to browse to all sites on the internet (i.e. Yahoo, Newegg, MSNBC, and others). The interesting part of this, is the Windows 7 machines resolve DNS to the sites, are able to ping and traceroute to the sites. They just won't open them in a browser.
Originally I was setting this up for a client, and I have replicated the issue in my lab.
I've attached my router configs for reference.
Any help is appreciated.
