Talk:Interactive Connectivity Establishment
From Wikipedia, the free encyclopedia
The terms NAT and Firewall should be carefully considered and contrasted in this topic. While both functions are sometimes combined in a signgle device, ICE's procedures are designed to optimize the NAT Traversal technique chosen, not to traverse firewalls. ICEs techniques (STUN, TURN, etc.) will typically succeed in crossing a router/nat/firewall device designed for minimal administrative managment (i.e. home/small business devices like those marketed under brands like D-Link and Linksys), but will frequently not cross a corporate firewall. This is because the corporate firewall devices are often configured so that UDP traffic is blocked.
