The above rule assumes that IPv6 has been enabled on the wan interface.
A general discussion of ping and its options along with IPv4 usage can be found in Section 3.12,
“ICMP Ping”.
IPv6 Usage Restrictions
The following is a summary of IPv6 restrictions in the current version of cOS Core:
• Management access with any cOS Core management interface is not possible using IPv6.
• IP rules using IPv4 and IPv6 addresses can coexist in the same IP rule set but a single rule
cannot combine IPv4 and IPv6.
• IPv6 addresses are not currently supported in IP rules with the following actions:
i. NAT
ii. SAT
iii. SLB SAT
iv. Multiplex SAT
• Routes using IPv4 and IPv6 addresses can coexist in the same routing table set but a single
route cannot combine IPv4 and IPv6.
• Routing rules using IPv4 and IPv6 addresses coexist but a single rule cannot combine IPv4
and IPv6.
• IPv6 cannot be used for VPN or with ALGs, IDP or traffic shaping.
IPv6 and High Availability
cOS Core High Availability (HA) does not fully support IPv6. Any IPv6 configuration objects will be
mirrored on both the HA master and slave units. However, if a failover occurs, state information
will be lost when one unit takes over processing from the other and IPv6 connections will be lost.
In an HA configuration where interfaces have IPv6 enabled and IPv6 addresses assigned, there is
no private and shared IPv6 IP for each pair of interfaces. Each interface pair will have the same
IPv6 IP address on both master and slave. A private IPv6 interface address for each interface in a
pair is not possible.
IPv6 and Transparent Mode
Transparent Mode in cOS Core does not directly support IPv6 since Switched Routes cannot be
defined for IPv6 networks (see Section 4.8, “Transparent Mode”).
However, it is possible to split networks transparently in the same way that Proxy ARP is used for
this with IPv4. Doing this for IPv4 is explained in Section 4.2.6, “Proxy ARP”. The only difference
with IPv6 is that Neighbor Discovery (ND) is used instead of proxy ARP. The method is otherwise
the same and the two can be used alongside each other to split both IPv4 and IPv6 networks at
the same time.
Using Neighbor Discovery Advanced Settings
This section will look more closely at configuring Neighbor Discovery (ND) for IPv6. In particular, it
