By default, all Opengear devices operate in IPv4-only mode. However they may also be configured to operate in dual-stack mode, enabling both IPv4 and IPv6 protocols.
Note: More exactly, kernel support for IPv6 is enabled by default however IPv6 is not allowed through firewall. So in IPv4-only mode you may notice self-assigned link local addresses beginning with fe80: and a ::1 loopback address. These addresses are inaccessible and do not indicate the IPv6 is operational.
To enable IPv6:
- Login to the Opengear web UI as root or an admin user
- Click System -> IP -> General Settings
- Check Enable IPv6
- Click Apply
Stateless autoconfiguration (SLAAC) is now enabled on all supported network interfaces (see below for limitations).
You may also configure a static IPv6 address by clicking the desired Interface tab, scrolling down to IPv6 Settings: Network and entering an IPv6 Address, Subnet Mask and Gateway.
Note that stateful/DHCPv6 configuration is not currently supported.
Most features, including console access, firewall customization and SNMP monitoring, are supported over IPv6.
The following features do not currently support IPv6:
- IP Passthrough
- Network failover
- VPN (IPsec, OpenVPN, PPTP)
- Per-serial port IP address aliases
- DHCP server
- TFTP & FTP servers
- PPP dial-in and dial-out
- Auto-Response SMTP alerts
- Network power control (PDU, UPS, IPMI)
- Remote syslog and log storage
The following features have limitations over IPv6:
- Custom console server mode base ports (e.g. SSH to 3000 + console port number) affect IPv4 only
- Cascaded console port access via the master uses the username:serial convention only
