Do I need to setup real public IP under fw topology as external inferface? And on firewall's general tab too? i don't find dynamic interface resolving option ...

thanks.

Te res says to add the natted IP to your topology for the FW and enable
dynamic interface resolving for remote VPN clients.

I have tried to change private IP published by fw for public router IP in Userc.C Securemote client config without success. When cient connects to fw, userc.c is overwritted.

gary, i find this morning this solution from checkpint's website, but I can not have enterprise acces. Can somebody send me please this solution via email??? At this moment, this problem turns very urgent.

Thanks.

If changing the userc_IKE_NAT value didn't solve your problem, then

I'd

suggest you get an fw monitor and an ike debug from the gateway.  With
the
ike debug you'll be able to see where in the process IKE fails and

why.

You
might be able to see from the fw monitor which packet IKE fails with.


1) To debug ike, run the command:
vpn debug ikeon

2) To turn on fw monitoring, run the command:
fw monitor -o mon.out

3) To bring the tunnel back up
Send traffic across the tunnel to initiate the tunnel

4) To stop the fw monitor, run the command:
ctrl + c to stop the fw monitor

5) To turn Ike debugging off, run the command:
vpn debug ikeoff
Review the ike.elg with wordpad and the fw monitor with ethereal.

Hi all,

i am trying to setup a vpn for securemote clients. My firewall is a
NGX HF02 under RHEL 3. This firewall is natted by ADSL router. Under
Smartcenter server I have activated UDP encapsulation (NAT traversal)
to establish vpns betwwen natted securemote clients and this firewall.
Well, this configuration does not works for me.

Under SecuRemote userc.C config file I see this params:

: (VPNHome.isildur
     :obj (
             : (192.168.67.193)
                     )
                     :keymanager (
                             :type (refobj)
                             :refname ("#_VPNHome")
                     )
                     :allowed_interface_ranges (
                             : (192.168.67.193
                                     :allowed_range (
                                             : (
                                                     :type
(machines_range)
                                                     :ipaddr_first (
0.0.0.0)
                                                     :ipaddr_last (
255.255.255.255)
                                             )
                                     )
                                     :is_ext (true)
                                     :is_natted (false)
                             )
                     )
                     :resolve_interface_ranges (true)
                     :ifaddrs (
                             : (192.168.67.193)
                             : (172.16.76.6)
                             : (192.168.100.65)

In this securemote configuration you will see this: is_natted
(false). How can I change this param under firewall, because is a
natted device ?? Do i need to use IKE over tcp to change this value?.

Thanks for your help.
