There is a new VPN service on the block, which may be of interest to a lot of you who are here looking at the information on PuTTY! Whether you are blocked by a firewall at your company, university or even country – Tunnelr enables you to gain unrestricted access to all Internet enabled services and content. Their tunneling services run on all major service ports, so in the event your company blocks SSH, POP3 or IMAP, you still are able to use the service on one of their forwarded ports.
