Hi tinc forum, I was setting up tinc server at home and try to use it while traveling. There are two questions for me to acheive this. 1. When I scan available ports my external IP address from outside using nmap, port 655 doesn't show up even though I've enabled on router. I'm using AT&T DSL and not fixed IP. I had to use port like 80 for tinc to work. Is this normal? 2. If I create a VPN connection to home from hotel, tinc server at home will try to connect my laptop using port 655 which is not open and not forwarded at hotel. Is there any way to get away with this? Can tinc use established connection without creating new connection from home to hotel? I'll appreciate any comments. Thanks in advance. Sincerely, Young. -------------- next part -------------- An HTML attachment was scrubbed... URL: http://www.tinc-vpn.org/pipermail/tinc/attachments/20090420/aa9c780b/attachment.htm
it almost sounds like your configurations are a backwards, Your server should not be "connecting" to your client on any specific port, but rather responding on whatever high port the client uses when initiating the connection. can you post the config files? Also, is your server a windows machine? If so, are you using windows firewall or any other security programs or antivirus + security suites that may need to be configured?

However, try adding TCPOnly = yes to the tinc.conf of your laptop. -- Met vriendelijke groet / with kind regards, Guus Sliepen <guus at tinc-vpn.org> -------------- next part -------------- A non-text attachment was scrubbed...
