That I would expect, but I just built the kernel last night, installed it, and am running it right now and I run into the same issue as I do with the older kernel :). Was there any magic foo that I needed to use to get FEATURES working properly, or was it supposed to be seamless? I don't know because I never had a need to fiddle around with the framework.. Is there a tool I can use (minus banging on the interfaces in C) to determine what the features are on the machine to diagnose why things aren't working for me? > You need an old user land or a new kernel to recover. Looks like I need an old userland, because a new kernel/userland combo doesn't seem to work as advertised :/... >> =A0 =A0I have both INET and INET6 built into my kernel and userland, but >> my immediate upstream router only supports IPv4 right now.

It's ok -- that's why I have two near workstations -- one for daily use and the other for testing :). Thanks! -Garrett
