Checkpoint will not pass IPX traffic and SNA is very much routable. You do need to encapsulate

as Elliot suggested, however bear in mind that your firewall will not be able to look higher up the stack.

Clarification:

Checkpoint doesn't care at all about SNA (or any other non-IP) traffic.  For example, a Checkpoint firewall will happily route IPX traffic as long as your OS is configured to do so.  Since SNA is non-routable, your firewall will only pass it if you can get your OS to bridge SNA.  So, Elliot's suggestion about encapsulating SNA is excellent (as long as you can get someone on both ends to configure the routers correctly).

Lior...Checkpoint can only pass IP traffic.  If you want to get SNA to flow
through the firewall, you will have to encapsulate the SNA traffic within
IP.

One of the ways you can do this is to use DLSW on a router.  SNA traffic
hits the router and is encapsulated within IP, flows through the firewall
to another router that will de-encapsulate the traffic.
