If you purchase a hardware router (lets say a linksys) don't you run into
lots of problems telneting / ssh / ftp into your linux machine? Or can you
forward httpd, ftpd, telnet, ssh and the such all to the linux machine on
the network? I know you can forward these services but I believe it doesn't
always behave normally? Problems with FTP transfers etc etc....

Comments on this issue?
