You get an error about being unable to establish an address... Hang on,
lemme give it a run...

At the time you explained that it had to do with ppp interfaces wanting to
share addresses with the Ethernet and sent a patch to circumvent this. I
tried the patch to no avail...

Yeah, I blew it. I had the wrong subnet mask set on the ppp interface at
the office end. I had routing problems too; I just assumed it was a RIP
problem and staticed everything. Pays to NOT set stuff up at 2am when you
started the day at 6 the previous am!! :-)
BTW, where should the 224 route point? On my system ("badpuppy") it's
pointing at the Ethernet; is that correct?
Thanks!!
