Definitely try without any INITS ('cept MacTCP) and try again.  If it's 
not too much bother, you might try dropping back to sys 6.0.5 (Just rename 
your sys 6.0.7 system folder, unbless it by dragging it's Finder out, and 
do a standard Apple install with the sys 6.0.5 discs.  You'll get a clean 
6.0.5 system folder, while still leaving your system 6.0.7 system intact.)

Ahh, more information.  The plot thickens.   So it's not the MacTCP 1.0 
MSS bug.  :^(   Are you on LocalTalk or Ethernet?  If LocalTalk what DDP/IP gateway are you using and what's it running?  As well what TCP/IP server s/w is on the VAX (I've come across my share of flaky VAX TCP/IP implementations.  
Wollongong's doesn't understand proxy ARPs, and I came across another 
whose name fortunately escapes me that didn't support PINGS!)  And finally, do you have another IP host, you can try, preferably a SUN?

I have the same setup as you, only DayStar's cache and I use Sys 6.0.5 on my IIci. (Gee, aren't you the keener.  :^)  Regardless of whether I run through 
LocalTalk and a K-STAR 8.0 FastPath 4, (Rev. J or higher), or my Apple 
Ethernet card (Rev. K or higher), everything works perfectly.  Good luck.
