Re: [FW-1] Automatic ARP on Windows 2000

Mon, 01 Apr 2002 14:17:13 -0800

I was looking on the web and I found a message about the the problem, telling that is a W2K problem not a FW problem. I searched the technet at Microsoft and I found an issue about the proxy arp functions in W2K.
Microsoft says that the problem will be solved in SP3.

Now I'm using the "fwparp" utility to publish the proxy arp addresses and is working fine.
By the way I put the local.arp file inside CONF directory, and it's not working.

This is a known bug with Check Point.  I ran into this and basically was told to use a local.arp file in the $FWDIR\conf directory (which works).  Check the release notes for FP2 when it comes out to see if it fixes the problem.

I had the same problem.  I ended up using the fwparp utility from Checkpoint.

Yes, I'm using only automatic NAT rules. But automatic ARP is not working.
That is my problem.

Did you use Automatic or manual NAT?

Hello everybody,

I installed three NG firewall modules (FP1) on Windows 2000, in a
distributed way, with the management module also on windows 2000, also, I
configured the automatic static NAT in the objects NAT dialog box and the
automatic ARP configuration in global properties dialog box.

The NAT is working very well but the automatic ARP is not.
The command   FW CTL ARP  shows an empty ARP table, so the return packet
doesn't reach the external interface of the firewall module.
I installed other firewall module on LINUX and the automatic ARP works fine.

Does anyone has an idea about why automatic ARP is not working on Windows
2000? Do I need configure something else in FW-1 or windows 2000?
Suggestions?
Best regards.

Teddy
