That doesn't strike fear into my heart... I used to run 2.6 on my IPX...
and it's what I deal with all the time at work...

I can get my hands on 4.1.4 and Solaris 2.5.1 and up...  How do I get the
same masquerading functionality (I've only used masq'ing/NAT under linux)
under SunOS/Solaris?  I'd prefer masq'ing and not a proxy setup if I can.
