The goal was to expose the LAN, mostly for fun, but what you're describing is certainly the more practical way of solving the port forwarding problem directly.
If I can't solve the routing problem, this might just end up being my fallback.

Do you need to route the entire network, or just access the NAS and other hosts? I think you could do something with SSH reverse tunneling, given you have a VPS.
On the NAS: ssh -R <desired_port>:localhost:22 user@<vps_address>
Then, once you've ssh'd into the VPS from anywhere else: ssh localhost -p <desired_port>
Now you're ssh'd into the NAS. The desired port could be anything but it needs to be the same on both ends. This also assumes your VPS has a static IP/dynamic dns, and you may need some way to keep the connection alive if it's going to be up for a long time.

Subject: [WLUG] Openvpn and Network mapping
So I've found myself in an unfortunate situation where I cannot port forward on my router. My solution to this was to setup an openvpn tunnel on my VPS that would allow me to access my LAN via a NAS that I keep online in my apartment. (In other words, my laptop would connect to my VPS, which would route to my apartment via my NAS, and thus expose the LAN). The big problem is that the network uses 192.168.1.0/24, and given that I cannot edit any router settings, I cannot change this. If I were to simply expose this subnet via openvpn, I wouldn't be able to access any other 192.168.1.0/24 address if I were connect to the VPN.
My plan was to try and use some iptables magic to map 10.24.0.0/24 to 192.168.1.0. Luckily, this works, thanks to the NETMAP extension (iptables -A PREROUTING -t nat -d 10.24.0.0/24 -j NETMAP --to 192.168.1.0/24, for the curious). However, the only way I can make this work is if I add the NAS as a gateway on all of the machines I want to connect to on my LAN, which is a bit sad (ip route add 192.168.255.0/24 via 192.168.1.69) .
Is there some way I can make this a bit more seamless? This isn't my least favorite solution, as I don't need to run the openvpn client on every host, but it isn't much better...

It turns out this option isn’t even available in the version of CUPS i’m running.
Looks like i’ll be trying to upgrade my ubuntu box this weekend and crossing my fingers that it solves the CUPS problems and doesn’t break anything else.

In general, CUPS is pretty darn reliable. But can you post some logs
from when the printer goes offline?

So this is a key issue to me, if printing from the iMACs (which
version of MacOS?) was un-reliable, then it points to a problem
somewhere else. As others have said, maybe the power is bad? But
have you checked your network as well? Do you have a switch or two
which are dropping packets randomly? Yes, TCP should handle stuff
like this, but maybe it's a wierd corruption issue somewhere?

Can you move your most used laser to the same network port/cable as
the inkjet and see if that improves reliability?

I've got a Brother MFC-8860DN laser printer which has lasted me over
10+ years at home and been quite reliable. The only problem is that
it's PostScript implementation is now getting long in the tooth. Best
damn $400 printer I've ever gotten.

Re: struggling w/ reliable printers on CUPS in small office
by Kevin W Stratton
Unless the UPS is very beefy, I wold not do this with laser printers.
When My laser printer is on the battery side of my UPS, it resets the
UPS when I start a print. I think it has something to due with a
current inrush for a heater that has to run before printing. Of course
newer printers may be better about this.

Re: struggling w/ reliable printers on CUPS in small office
by E Johnson
One thing that occurred to me:
I had a problem like this rather frequently in the last apartment. It had
electricity issues: the ancient refrig was on same circuit as half of the
apartment --including the elex outlets I had to use for the computers &
printer, etc. The lights used to dim slightly whenever the refrig
compressor came on. I used to hear the printer resetting itself several
times/week. The printer and CUPS often disagreed -- quit working together. This
is a decent HP Deskjet, on the compatible list. But printers seem to be
sensitive beasts.
Restart CUPS usually fixed the problem, altho occasionally I would have to
completely disconnect the printer, power, data cable & all, then wait a few
min before hooking it all back up, then restart CUPS.
Now here at the new place since last May, there are no fluctuating elex
issues, and no CUPS - printer issues either.
May I suggest, if you don't have already: plug all the printers into a
decent UPS (rather than zip strip or whatever), which should keep the elex
supply steady for your printers.
I have a spare UPS here that I am not using. I bought it several years ago
for just this reason, but it works only with grounded outlets which we did
not have at the old place (they were "fake" grounded). I would gladly
contribute this UPS if you would like to see if it helps. I am in Worcester.

Re: struggling w/ reliable printers on CUPS in small office
by Kevin W Stratton
I have had this problem with a couple of older distributions of linux.
The problem now does not occur with the same network printer that I have
had for a long time. I have a single user setup, so I do not know if is
relevant information. Perhaps one machine on the network has a buggy
version of CUPS?
Doing a quick google search I found:
https://bbs.archlinux.org/viewtopic.php?id=202022
pypi suggests considering changing the ErrorPolicy for a similar
problem. I have never done this, so good luck.
