I don't know smoothwall but most likely you will either

select the protocol type with a drop down menu (tcp-udp-47...)
have it happen automatically when you forward 1723
be screwed (eg have to customise netfilter?)

if you get stuck monowall http://m0n0.ch/wall/ has all this functionality
and is a doddle to set up

make sure that the internal vpn server has the correct gateway setting.


re the sme 6 ups have a look at
http://www.contribs.org/contribs/rmitchell/smeserver/howto/powstatd%20HOWTO%
20for%20sme%20server.htm

I'd be interested in how you get on - I always plug in the ups and then
never get around to setting up the software (ext3 seems much more resilient
to power failures than ext2 ever was)


cheers

Mark

So how do I forward a protocol vs TCP/UDP

Or do I need to hack the IPTables config?

That's a fairly common problem.  If you read the docs closely, you'll
observe that PPTP uses TCP port 1723, and IP protocol 47 (*not* TCP port
47).  Allow protocol 47 (GRE), and you should be all good.  By way of
explanation, have a look at /etc/services (the list of TCP/UDP ports) vs
/etc/protocols (the list of IP protocols) on any lunix box.

Cheers
