RE: [FW1] Issues with Windows 2000 server?



The release notes for fw-1 4.1 SP3 says it supports win2k for the gui client
as well as the firewall module.

Subject: [FW1] Issues with Windows 2000 server?


I plan to upgrade Checkpoint 2000 4.1 to a Windows 2000 server.  I have saw
some people say it does not work well and some say no problems.  Does anyone
know any problems or limitations on 2000?   The Checkpoint site says the
firewall module will run on 2000 but not the GUI client?  Any help would be
appreciated.

Subject: RE: [FW1] NAT Issue


One thing I forgot to mention is that I cannot connect to the firewall :-( 
 
I see a serial interface setup but when I try to connect it fails.I have
tried both COM1 and COM2. Can anyone tell me how to connect to the Netra T1
through a serial interface, from an NT box?
 
Doing a telnet/ssh to the firewall also fails, although I have rules defined
on the firewall
 
Thanks,
 
Sumit

Did you look into your static routes defined on the OS?! The FW-1 on Solaris
depends on static routes and arp entry defined on the Solaris environment.

You must tell to your firewall, if you have some router inside your internal
network, that the next hop to the arp entry must be the router interface.
And also define static routes for every address you are NATing.

If the routes were stabilished and didn´t setted on a rc script you probably
lost them when you reboot your machine. 

Here you are some examples: 
# ARP commands used for NAT (where xx.xx.xx.xx is the valid address) 
/usr/sbin/arp -s  xx.xx.xx.xx 7:0:20:8d:fd:a7 pub 

# necessary routes for STATIC ROUTES (where xx.xx.xx.xx is the valid address
and yy.yy.yy.yy is the internal address) 
/usr/sbin/route add xx.xx.xx.xx yy.yy.yy.yy  1

Hi, 

I have been asked to look after the firewall in our company NOC. The person 
who setup the NOC and the firewall has left. The problem which I am having 
is that NAT'ing is not working, although it seems to be defined correctly. 

The logs don't tell anything useful. The firewall is CP 4.1 installed on 
Netra T1. I really need to get it going. Any suggestions to 
troubleshoot/resolve this problem will be appreciated. 

Thanks, 

Sumit
