Let me guess....you aren't using a "business" account with a guaranteed static IP address. Here is how it works, you configure for DHCP and get a lease. Then you take that IP address and punch it in as a static, reboot, cut a new license key for Checkpoint, and you are good for a couple days.... Then your lease expires, and someone else is leased your current address and the process repeats. The solution is to get a true static IP address. However, I have seen some peculiar activity even with a static when using DOCSIS and "baseline privacy". It seems that the ARP entry on the router for my static gets considerably aged and the only way to renew connectivity is to reset the DOCSIS modem which performs bootp to get a new management IP address and it's bootfile which has a bunch of SNMP mibs entries set...otherwise, you have to telnet into the UBR router and clear the old ARP entry (but that is hard unless you have friends at the cable co..heh) Checkpoint doesn't like to cut new license keys, wonder how you are managing this. 8) ----- Original Message ----- From: "Peter Parnell" <[email protected]> To: <[email protected]> Sent: Friday, December 01, 2000 8:26 AM Subject: [FW1] NT Server 4 Firewall-1 4 WEIRD Problem - HELP > > I have an NT4 SP6 machine with Firewall-1 4 , attached to an SDSL modem with a 1Mb pipe to my ISP. I am using NATand I am blocking all NBT traffic.Here is the weird problem....It can be 12 hours, 2 days or 3 days, but eventually my external interface stops passing packets. NT Event viewer shows no events. When I reboot the Nt Server, i receive the infamous IP Conflict message telling me that I am in conflict with the mac address of the CISCO router on the other side of my DSL Modem. I have tried different NICS to no avail. To solve the problem I need to configure my external NIC for DHCP, disable Checkpoint. restart and obtain an IP address from the DHCP server which has a reservation for my external NIC. After successfully obtain my IP, I again configure for static IP, enable Checkpoint, restart and all is well again until the next time. I have tried a switch in between my Firewall and the Modem thinking that broadcast traffic was messing me up. No help.
