TBMEM, SU MacIP, Gateway address

[Mark Powers]

I have three quick questions, hopefully some kind soul out there can answer.
 
1)  I can't remember how to setup the TBMEM parameter to define virtual memory.
 
 
2)  Under Stanford MacIP the application launches just fine, FTP seems to
    work, but when I start a telnet session the OPEN message appears then
    the window closes ?
 
3)  Possibly related.  The MacTCP CDEV won't allow me to change GATEWAY address
    or define name servers...
 
If someone could point me in the right direction on these I'd really appreciate
it.
