Creating GRE tunnel

Hello,

We are migrating from Cisco router to Checkpoint security Gateway. Cluster.

We can not figure it out how to create GRE tunnel on Checkpoint. Version is 81.10

From cisco we have such config:

ip address 10.15.0.1/30
tunnel source IP1
tunnel destination IP2

We have to use secondary interface, because cluster doesn't support VIP alias. Also we have only one IP address as the mask is /30.

in this situation we have to set that interface like that:

GW1 eth2: 192.168.1.1/24

GW2 eth2: 192.168.1.2/24

We put VIP: as IP1 (i.e. 88.77.66.55/30)

We are out of ideas, how to create GRE tunnel in Cluster environment in correct way and set up correct IPs. We already read documentation.

For GRE tunnel we need:

IP address; Peer address; Local address; Remote address.
