Hello all, I'm new to the list so if my question has already been discussed here I'm sorry, but here goes my question... I've got an ISA Server with 2 NICs: one internal (192.168.0.1/24) and one external (10.0.0.150/24) connected to my ADSL modem (10.0.0.138/24). To dialin into my ISP it setup a VPN (PPTP) to my ISP. Now my problem, if I install ISA Server I can't connect to my ADSL modem and it won't connect to my ISP, because ISA blocks all IP traffic. So if I open the PPTP ports to pass through, I can connect to my ISP. But then it allows all traffic come thru!!! Including those of the Internet without a prober filter! I'm probably doing something really wrong, but can someone help me? Or does anyone has the same setup? Thanks in advance, Alain
