Yes. I just tried it. But you don't have to use the dynamic DNS
numbers that LSPPP puts in IP-UP.BAT, although there shouldn't
be any reason not to.

It's not a trick to fool your ISP. In order to resolve domain names
you need to use a domain name server. This is part of the service
that an ISP provides. Either they tell you what they are or they are
given during the PPP handshake. It really doesn't matter all that
much, unless your software does not support dynamic DNS and your ISP
doesn't tell you what they are, in which case they're pulling a trick
on you by taking your money and not providing DNS service.

You can accomplish the same thing by writing the values that are in
path.cfg directly into wattcp.cfg, without using include=path.cfg.

Whatever method you use, you should be able to see the difference
between the arguments to EPPPD and the values that go into path.cfg
or wattcp.cfg after the packet driver is loaded.

All I know is that it's the MRU (maximum receive unit) on the remote
side. It is almost always 1500, which means you can set your MSS up
to 1460. I'm really not up on this stuff. I have MSS commented out
in my wattcp.cfg and just run with the defaults.
