How to enable IPv6 native mode on Sophos SG UTM
- Enable IPv6
- Enter IPv6 fixed IP address , Netmask and Default GW address on WAN Interface
- Add IPv6 address to Internal
- Add Prefix Advsetis….. to intermal
You should able to see the WAN IP of IPv6
Test:
Go to "Support" -> "Tools"
Internal IPv6 address: fda8:06c3:ce53:a890:0000:0000:0000:0004 (Unique Local )
- enable IPv6
- force the UTM to request a prefix (not sure why I needed to do it)
- add <prefix>00::1 as the IP address on the LAN interface (64-bit mask)
- advertise the prefix on the LAN interface using stateless integrated server
- enable automatic renumbering

Throughput and Performance |
|
|
Firewall Throughput |
This
is raw throughput, the measurement of traffic flowing through the firewall
without necessarily being subjected to antivirus scans, content filtering,
intrusion prevention, data loss checks and similar steps. The figure can also
vary by protocol and packet size. Some vendors may cite 1500 Byte TCP whilst
others 64 Byte UDP |
|
IPS Throughput |

Remark |
When compare between different vendor on performance, it need to confirm they are using the same assumption to provide the figure (e.g. Vendor A will enable all features when testing throughput but Vendor B will disable all features) |
