address conversion - is it possible?

[koresnordic]

Sorry, new to this, so this may be a stupid question. We have a sonicwall soho3 firewall with vpn installed. Directly attched to the LAN port of this is a computer which acts as an e-mail server. This has two network cards. One setup as 217.37.218.xxx, and the other as 192.168.0.1 (because we are using ICS to allow all the network to access the Internet via this computer). This has so far worked fine. Remote users can connect the e-mail server without a problem. Now we wish them to access one particular computer on the main network. It is know as the address 192.168.0.254. What I need is when the firewall gets a request for http on address 217.37.218.xx2 to convert it to 192.168.0.254 and pass the request on. This system has a lot of other data thatwe do not want to be become publically available so getting a firewall with a dmz is not a viable option. Is what I want to do possible? if so how?
