Watchguard X55e - Can I turn off NAT?

I have a Watchguard X55e. I want to replace my Sonicwall SOHO3 with the X55e. I currently have a /29 subnet and do not use any NAT on my sonicwall.

I also have two subnets routed to my router, one subnet goes to my sonicwall and the other subnet goes to some unprotected PCs.

Is it possible to configure the X55e to operate without NAT? And is it possible to have the X55e handle both subnets?

The answer should include instructions on how to configure the X55e this way.

Thank you.

If you are running version 10.x of software on x55e then NAT CANNOT be turned off.

http://www.watchguard.com/help/docs/edge/10/en-US/index_Left.html#CSHID=en-US%2Fnat%2Fnetwork_addr_translation_about_c.html|StartTopic=Content%2Fen-US%2Fnat%2Fnetwork_addr_translation_about_c.html|SkinName=Edge%20%28en-US%29

Read under "NAT behavior".

If you are running ver 11.x then you get XTM software and also access to XTM WSM; in bigger boxes there is option to put the firewall in drop-in  mode where NAT is disabled; not 100% sure but think same can be done on x55e as well.

Thank you.
