Eyeball AnyFirewall™Server provides a scalable NAT
and firewall traversal solution for SIP end-points based on IETF
standards and drafts such as STUN, TURN and ICE:
- STUN helps an end-point to discover whether it is
behind a NAT/firewall and determines the public IP address
of the firewall and the type of firewall. It is helpful in
establishing peer-to-peer calls between endpoints where at least one
of the end-points is behind a NAT a or firewall.
- TURN provides a far-end NAT traversal technique
where a media relay server connected directly to public Internet is
used to help media transport between end-points.
- ICE provides a SIP offer/answer model for
end-points to exchange multiple candidate IP addresses and ports
(such as private address and TURN server address) so that end-points
can always establish a connection between
them. For TURN, Eyeball AnyFirewall Server supports UDP and TCP
transport. It also supports HTTP/HTTPS tunneling for all
communications such as SIP signaling and media data.
