Question

problem with routing

Asked by: FiremanFpG

hi,
i have a checkpoint utm-1 270 r65.
 i have 2 seperated networks 192.168.25.0 mask 255.255.255.0 and another network 172.16.1.0
all users and servers sit on the 192.168.25 network.
the 172 network is connected physically to a server on my network that has 2 nics
i installed routing and remote support and configured the LAN ROUTING option.
i configured the nics:
172.16.1.1 255.255.255.192 no GW
192.168.25.9 255.255.255.0 192.168.25.254   (254=checkpoint utm-1 270 router ngx)

if i try from a station to ping 172.16.1.1 i can`t until i add route
route add 172.16.1.0 mask 255.255.255.192 192.168.25.9
then i can ping it
i tried to configure the route on the checkpoint either by using the webui and by using the ssh - the route appear but it doesn`t work for all my network stations, i tried rebooting the checkpoint.
still didn`t helped, i`m stuck and i really need a solution

here is the routing table from the checkpoint: (i removed the real internet IP`s and the atm gw ip)

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
REALINTERNETIP *               255.255.255.192 U     0      0        0 External
172.16.1.0      192.168.25.9    255.255.255.192 UG    0      0        0 Internal
192.168.25.0    *               255.255.255.0   U     0      0        0 Internal
192.168.12.0    *               255.255.255.0   U     0      0        0 DMZ
10.59.0.0       *               255.255.0.0     U     0      0        0 Lan1
127.0.0.0       *               255.0.0.0       U     0      0        0 lo

This is correct - nothing on your LAN knows about the 172.16.1.0 network except your 192.168.25.9 machine. You'll need to make sure that all of your network devices use a gateway that knows how to route to 192.168.25.9. You'll also need to make the route on your CP FW permanent so it always sends traffic destined for the 172.16.1.0 net to 192.168.25.9.

What do you mean by 'it doesn't work for all of my stations'? If you're on a device and it can't get to 172.16.1.x, run traceroute and see where the path fails. Then go to that routing device and make sure a correct route exists.

i pasted the routing info from the CP FW.
i tried pinging even from the cp fw itself (by using ssh) to the 172.16 but nada, i can reach 192.168.25.9
i posted the route i added to the cp fw (it`s in the route table)...

any ideas why the cp fw isn`t accepting it..
maybe i need to do something else after i add the route by using the webui ?

i ment that it doesn`t work for any station, even if i traceroute i see that it goes to the cp fw and then nada (even though the route was added)

Hi,

This may be being stopped by anti-spoofing - make  sure you are logging implied rules (configure in global properties) check your tracker logs and see if there is anything relevant in there.

You need to create a 172.x.x.x network object and configure it in the anti-spoofing rules In the topology tab for the Internal interface.

Please post any relevant logs you see in Tracker

it`s a good progress - after cancelling(for the test only) the anti spoofing - i can now ping the 172.16 network
under the  topology i have 3 defined - external,dmz,internal
in the internal i have selected - "network defined by interface ip and net mask"
i think i should change it to specific and create a group and all network address behind the internal ?
or shoud i create a new topology with the 172 properties ?

"i think i should change it to specific and create a group and all network address behind the internal ?"

Exactly - under the Internal topology you should create a group of the networks which CheckPoint can expect to see traffic from - i.e. 192.168.25.0 and 172.x.x.x

Push the policy and you should be sorted!
