Remote support/connections through locked down firewalls using port 80 only

We are a pc repair centre that offer telephone support to our clients, and for certain clients on fixed IPs we connect to there servers using windows RDC. We would like to be able to connect to all our clients even those behind locked down firewalls (sonicealls etc...). We have looked into PC Anywhere but this requires a gateway pc at the customers end with the software installed and the use of ports 5631 (TCP data port) and 5632 (UDP status port). We've seen other much larger comapnies use services such as LogMeIn which have allowed connections to machines behind firewalls that have everything baring port 80 locked down both in and out. We like the idea of LogMeIn but want software that we can host on our own servers not someone elses. Any ideas?

I use UVNC's SingleClick option. It is great. The client has to initiate the conection by clicking on a little file you send them <200K, and it creates an outgoing connection, so no ports have to be configured. Offers encyption, and does not install anything on the client computer. Have a look at the following for a better description and link to the free application.

Did almost everything that we needed and especially pleased that it's customisable. Only floor we found is that the listening ports couldn't be altered so for sites behind locked down sonicwalls (port 80 trafic only), we had to also unblock the ports used by VNC.

If only we'd of found this product sooner

Yes. It will work on most firewalls without configuring because outgoing ports are open by default, but on those that have been locked down it won't. Then again, that is why you lock them down; you wouldn't want Johny in the parts room, using similar application with his buddy at home, which is a concern because this bypasses most basic security .
Thanks mendmycomputer.
Cheers !
