Ipv6; Sip - Secure Computing SG300 User Manual

IPv6

Check Enable IPv6 to enable IPv6 routing and packet filtering. Support for IPv6 is
currently limited.
Note
You must also enable IPv6 for each connection that supports IPv6. See the section
entitled Direct Connection towards the beginning of this chapter.
When IPv6 is enabled, site-local addresses are assigned to LAN connections, the site-
local DNS server address (fec0:0:0:ffff::1/64) is assigned to LAN connections if
the DNS proxy is enabled, router advertisements are sent on LAN connections and 6to4
tunnels are created on Internet connections.
Additionally, a default set of IPv6 packet filter rules are enabled. These rules are
stateless (as opposed to the IPv4 packet filter rules which are stateful). The default rules
only support a single LAN connection and a single WAN connection. These rules may be
customized—refer to the Custom Firewall Rules section of the chapter entitled Firewall.

SIP

Note
SG565, SG575, SG580, SG635, and SG710 only.
The SG's SIP proxy allows SIP software clients (like kphone, linphone, SJphone) or SIP
hardware clients (Voice over IP phones which are SIP-compatible, such as those from
Cisco, Grandstream or Snom) to work from a private network (such as your LAN) behind
a masquerading firewall (such as the one on the SG).
SIP (Session Initiation Protocol, RFC3261) is the protocol of choice for most VoIP (Voice
over IP) phones to initiate communication. By itself, SIP does not work from behind
masquerading firewalls, as the transfered data contains IP addresses and port numbers.
