Port forwarding in SonicWall firewall

Hello All
i've just bought a Sonicwall TZ 170 firewall. I'm trying to configure the port forwarding... i suppose it is to be done through Nat Policies ...i just need to do it for SMTP(exchange server ) , RDP and PPTP.
Do i have to configure network objects for these things???

Can anyone has more information on how to do it??

Who is Participating?
SMTP is tcp 25
rdp is tcp 3389
pptp is tcp 1723

Thanks for the quick info..In your link page it doeasn't describe the destination IP address of the exchange server to forward the port number.
i have tried using Public Server Wizard in Firewall--> Access Rules and created a Rule for Mail Server.
It also created the NAT policy automatically..
i haven;t tested it yet coz i could only test it on weekend..

if you have some more information for rdp and pptp and how to make them more secure ,,

Thanks again

pptp is probably one of the weaker vpn solutions at this time. I would suggest using and IPSEC VPN. IPSEC can be setup LAN to LAN of Client to LAN. Here's the spec sheet for your firewall.
It looks like you have 2 site to site  VPN's and client to site are optional. I suggest implementing IPSEC VPN for RDP and then you shouldn't need the pptp at all. Close the PPTP and RDP on your firewall and just use IPSEC. Some people may not agree that IPSEC is necessary for RDP however when it comes to security paranoia isn't a bad thing.
