On Windows NT firewall engine, be sure that "enable IP routing" is checked. Thank you, Cathy Tebo Federal Home Loan Bank of Chicago Technical Security [email protected] ____________________Reply Separator____________________ Subject: RE: [FW1] Anti-spoofing Author: "Roelandts Guy" <[email protected]> Date: 7/27/01 8:55 AM Josh, What is the problem ? We have an Nt box with 5 interfaces, 4 of them are in use without problems ...

I am attempting to run three interfaces on my NT checkpoint fw-1 SP3 box, in the same configuration (internal, external, DMZ). but apparently NT can not route between three NICs, is this something I have to run a UNIX, or Sun box for ? ...what about windows 2000 advanced server? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Don Leeper Sent: July 25, 2001 9:53 AM To: '[email protected]' Cc: '[email protected]' Subject: [FW1] Anti-spoofing I was wondering if someone could give me your input on anti-spoofing. I have 3 interfaces on my FW: DMZ 192.168.2.1 External 63.64.1.1 Internal 192.168.1.1 I have a DNS server and web server sitting on the DMZ. Which needs to be open to the public. I have my email server and one web server on the Internal. They need to be accessible to the public as well. All addresses that are for the public are nated. Could someone tell me how you would set up the anti-spoofing on the FW that won't affect my setup but protect me? I noticed in my logs that someone was trying to get in using private addresses. Thanks for your help in advance. (I did look it up but I think its better to hear how others do it!) Kind of confusing....
