However, won't it still configure an autonomous IPv6 address from radvd information even if I remove the IPv6 IP? Is there any way to disable IPv6 completely on the probe? Or do I have to do something to ensure it doesn't get autonomously configured on the radvd side? Hello, Due to security concerns I have my probe plugged in into its own network port on my gateway server, that way I can easily control whether or not the gateway does RA on this port, which DHCP details it sends out, which firewall rules are applied, etc. An alternative would be putting the probe in its own VLAN, but my main switch is not VLAN-capable. In your case you can try firewalling off IPv6 from the probe and then rebooting it, so even though it has an IPv6 address, it can never connect to anything on IPv6, and hopefully it will just use only IPv4 from the start. -- With respect, Roman -------------- next part -------------- A non-text attachment was scrubbed...
