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?
