If there is SNAT rules on eth1, need to add exclude rule
.. code-block:: sh
# server side
set nat source rule 10 destination address '10.0.0.0/24'
set nat source rule 10 'exclude'
set nat source rule 10 outbound-interface 'eth1'
set nat source rule 10 source address '192.168.0.0/24'
# remote office side
set nat source rule 10 destination address '192.168.0.0/24'
set nat source rule 10 'exclude'
set nat source rule 10 outbound-interface 'eth1'
set nat source rule 10 source address '10.0.0.0/24'
To allow traffic to pass through to clients, you need to add the following
rules. (if you used the default configuration at the top of this page)
.. code-block:: sh
# server side
set firewall name OUTSIDE-LOCAL rule 32 action 'accept'
set firewall name OUTSIDE-LOCAL rule 32 source address '10.0.0.0/24'
# remote office side
set firewall name OUTSIDE-LOCAL rule 32 action 'accept'
set firewall name OUTSIDE-LOCAL rule 32 source address '192.168.0.0/24'

you additional information for using /31 subnets on point-to-point links.
