I am trying to enable outbound PPTP VPN connections through our ISA server. I enabled IP Routing and PPTP passthrough but when I did that none of my Firewall clients could connect to secure (HTTPS) websites. I have found that disabling IP Routing corrects the problem with the secure sites and my outbound PPTP VPN connection still works. I guess my question is do I really need IP Routing enabled? Is having it disabled going to cause any problems? Thank you,
