ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308
These are the options:
• IPv4-only mode. The VPN firewall communicates only with devices that have IPv4
addresses.
• I
Pv4/IPv6 mode. The VPN firewall communicates with both devices that have IPv4
addresses and devices that have IPv6 addresses.
Note: IPv6 always functions in classical routing mode between the WAN
interface and the LAN interfaces; NAT does not apply to IPv6.
Note: When the Load Balancing Mode radio button is selected in the Load
Balancing Settings section of the WAN Mode screen, the IPv4 / IPv6
mode radio button is dimmed, preventing you from selecting it. You
can select the IPv4 / IPv6 mode radio button only when the Primary
WAN Mode radio button is selected.
To configure the IPv6 routing mode:
1. Select Network Configu
ration > WAN Settings > WAN Mode. The WAN Mode screen
displays:
Figure 27.
2. In the Routing Mode section of the screen, select the IPv4 / IPv6 mode radio button. By
default, the IPv4 only mode radio button is selected, and IPv6 is disabled.
