Cannot remote telnet thru sonicwall

I am new to using firewall appliances and need some help.
I have a Cayman 3220H DSL (Bellsouth)  Modem/Router using PPPoE and one static IP. Originally I had the router set to pinhole any telnet/port 23 to our unix box with a static private IP and it worked perfectly.
We installed the sonicwall Tele3 and set the router in bridge mode and let the sonicwall do the PPPoE authentication and DHCP to the rest of the PC's on the network but the unix box still has its static private IP. From behind the firewall telnet goes right to the box no problem but I cannot access telnet remotely.
How do I setup to allow remote telnet thru bridged router thru sonicwall into unix box?

You must allow the sonicwall to let telnet go through to the LAN behind...
- Go to access -> service tab
- click on telnet -> DMZ in and enter IP address
as i don't see any option to route directly to the LAN, you'll have to define a DMZ-IP, where you setup the telnet-server.
If the telnet option isn't available, you'll have to "add service" first

As I haven't any of these sonicwalls, I can't really tell you definetly... but in principle that should be the way (my knowledge comes from an online-demo on sonicwall homepage)

so good luck
Holger

Thanks for the response holger but my sonicwall does not have a DMZ option in the advanced tab could it be done another way?

Disregard my question!
 I just forgot to change the default gateway IP of my unix box to reflect the sonicwall that is actually doing the routing....DUH!!!
Thanks again "holger" for trying to help me!
