VPN and SmartLSM doesn't works

Marco32 — Fri, 17 Mar 2023 18:13:36 GMT

Hi there,

I'm trying in my LAB to create a VPN from a CheckPoint Gateway and several 1570R managed by SmartProvisiong.

Every SMB is connected to a SmartProvisiong of a CMA in my MDS and use a cellular interface to reach my network.

The CheckPoint Gateway is managed by the same CMA.

I followed SmartProvisioning Adming Guide, but I see only some tunnel_test packet and no other traffic.

I don't have any route to EncryptionDomain in CheckPoint Gateway even if I try to use permanent tunnel.

The EncryptionDomain of the Gateway is configured with a group containing a subnet.

The EncryptionDomain on SmartLSM Gateway is configured Manual (on Topology page) witha range of IP that are used as NAT.

Traffic coming to Gateway from it's EncryptionDomain is dropped as:

# fw ctl zdebug + drop | grep 20.20.20.100
@;389050;[vs_0];[tid_0];[fw4_0];fw_log_drop_ex: Packet proto=1 20.20.20.100:1 -> 10.10.10.9:0 dropped by fw_log_ip_routing_failure Reason: IP routing failed (ipout routing failure);

Can some one help me?

Regards

Run command -> ip r g 20.20.20.100 and see path its taking. Confirm first it is correct and if so, we can run fw monitor to verify.

#ip r g 20.20.20.10
20.20.20.100 via 10.176.2.200 dev eth1 src 10.176.2.90cache

#ip r g 10.10.10.9

RTNETLINK answers: Network is unreachable

20.20.20.100 is on Gateway side , 10.10.10.9 is on SMB

Traffic need to start from 20.20.20.100 to 10.10.10.9

Can you draw simple diagram showing how this is configured and whats supposed to access what on the other side? Even basic paint diagram would help : - )

Cheers.

We need to find out WHY that IP shows unreachable, thats the key here.

Hi the_rock,

main issue seems that no route are present on Gateway and on SMB. I see tunnel_test from SMB to Gateway but VPN is marked as down.
