Greetings, I am looking to set up a static tunnel on a sandbox network in my lab. This network is connected only to the Internet and has a firewall managed by IT. The network will be used to host servers that should be reachable over the Internet via IPv6. I have attempted configuring a tunnel on a system, but it is blocked presumably by policy on the firewall. I have spent some time reading through the FAQs and it is not exactly what open port request I must make to IT. This is what I am guessing.. someone please confirm or assist. TCP 3874 - My IPv4 to tic.sixxs.net IPv4 UDP 3740 - My IPv4 to PoP IPv4 protocol 41 ??? UDP 5072 - My IPv4 to PoP IPv4 Am I missing anything? Thanks in advance! PW
