[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] RE: [FW1] Web server in DMZ
Ivan, The format of your static route should be as follows: route add -p <external valid IP address> mask 255.255.255.255 <internal non-routable IP address> The intent is as follows: Anything that is trying to get to that valid address should be forced directly to the internal IP address of the server in question (or the router that will get it there if a router is between the firewall and the destination server). Under NT 4, I also strongly recommend sticking to Check Point's recommended local.arp format to ensure the firewall is always ARPing for the external addresses in question: <external IP address><TAB><MAC address of firewall NIC answering for that address> Hope this helps.

Yes, we have added the route to the Route Table as below route add -p internal_ip mask 255.255.255.255 DMZ_interface metric 1 We also added the arp but we created a bat file to run during startup for the arp (we run this bat file before we do the test, will there be a problem) arp -s external_ip Mac address FW1_external_ip We do not have a local.arp file in the c:\winnt\fw\state directory, can we just create it and input the Web server External_ip and the Mac address of the FW external_ip. We are using Stat NAT. How would I check if the FW-1 is answering the ARP request for the NATed address? We are still unsuccessful. What else did we missed?
