Using VNC (Remote control client) over broadband

I've been playing with VNC remote access client between PCs on my home
network, and it works well.

http://www.realvnc.com/faq.html#internet

However, that's only with a view to installing it on a couple of friends
and family's machines to help next time they phone me with a problem.

I experimented with a friend (he's on NTL 1MB, I'm on ADSL 500k) despite
opening ports 5800 and 5900 on both of our firewalls, we could not connect.

Anyone managed to get it working, and if so is it usable over 500/250k
d/s:u/s links ?

TightVNC is better in my opinion (file transfer for one thing)

You should be able to select what port you want to use in the software. You
have opened the firewall but don't forget you are likely to need an inbound
NAT translation rule too.

It works fine on standard 512K broadband.

I used to use it on VPN over ADSL connections to a number of clients -
it works well.

You may have opened the necessary port on the VNC server side (and I'm
assuming you've set up port forwarding correctly), but are you sure
your respective ISPs aren't blocking it?

It's certainly possible to use it. The way I do it is to use ssh to
establish a secure connection to the remote site and forward the VNC ports.
Once you can do ssh you can forward pretty much anything down the secure
link.

I use TightVNC - same thing -

Yep, done it from UK to Spain, and to Cyprus. The latter was a dial-up,
and whilst painfully slow, it worked.

Yes, I have connected one PC to another here out modem back in ADSL.
(easier not to deal with the unfixed IP on dial-up)

I have not done a connection via ADSL both ends, but do think it would
work from that experiment.

I use it from work (1Mb256Kb ADSL) to access my home pc (1.5Mb/256Kb NTL
cable) without problem.
I open ports 5900 & 5901 though, not sure if that makes any difference.

I prefer TightVNC personally, a very handy tool.

Have you forwarded the ports on the router if you're running a NAT
setup?

That's the way I do it too. I'm not aware of any free VNC
implementations which are secure by default so ssh tunneling is probably
the easiest way to secure it.

Thanks to all for your responses.

We did try opening ports 5800 and 5900-5910 in both directions, and also
port forwarding to the LAN side ip addresses of the machines, without luck.

I've got a Solwise SAR-715 router, my NTL connected friend uses Tiny
personal firewall. We'll try again this week !
