WAP + gateway + Switch (3COM OfficeConnect)
IP 192.168.30.1 (obtained from DHCP of Modem?)

Linux Machine (Mandrake 10)
IP 192.168.30.54 (obtained via DHCP of 3COM gateway)
I can do:
telnet 192.168.30.54.
But if I do
telnet [My ISP IP]
then I get into a telnet session of the DSL Modem. To solve this I set the NAPT Default server of the DSL Modem to 192.168.30.54. When I now do
telnet [My ISP IP]
I get a connection timeout.
Help is very welcome

Don't know why you want to go back to insecure telnet instead of ssh but you are trying to go back out to the internet (by using ISPs IP) and then back in.
You would need to open 23 port and map it to your linux box.
Or find some way of detecting that it is internal and route it internally. Why not add a IP for your external domain and then use that to telnet
/etc/hosts
------------
192.168.0.54 x.diddily.com
and then telnet to x.diddlily.com
where x.diddily.com is your external domain name for your external IP.
