What I was referring to was using one of the dynamic DNS services
and using openvpn. I don't see how one would give you problems with
the other.
I didn't suggest, or mean to suggest, that I had any problem with dyndns
because I was running OpenVPN.
The only problem I have had with dyndns is that I haven't been able
to use a domain name I bought from EuroDNS,
although both eurodns and dyndns mention the other in their documentation.
With openvpn, it depends on how you set it up as to if you are
joining the remote network, or just the remote machine.
I'm just setting up the remote machine as a client.
I guess I would quite like to set up a remote LAN,
and join that to my local LAN.
I didn't know that was possible with openVPN.
(Are you using a bridged
connection on one or both ends, or have you set up IP tables and
routing to do the same thing?)
I'm running shorewall on my local server,
and allow openvpn traffic through with that.
(I also had to open a pin-hole on my local ADSL modem.)
With ssh it is usually a machine to
machine connection, but you can also get fancy with port forwarding
over ssh. I used to forward port 25 over an ssh connection so that
my outgoing mail was coming from the "local" machine as far as the
mail server on the remote machine was concerned.
I'm not very clear on this sort of thing,
but your remark makes me wonder if I could use that idea
to get over a completely different problem I have:
My college has set up mailman so that list-owners
(and I presume anyone else) has to post email
from within the college system.
I would prefer to send email from home, where I can use KMail,
although it is very little trouble to ssh into my college account,
and send email from there.
