Description

Hello,

the user interface allows the `Default valid lifetime` field to be set to a lower value than `Default preferred lifetime` field. When this is done, radvd will not start, due to

AdvValidLifeTime must be greater than AdvPreferredLifetime in /var/etc/radvd.conf, line 18

Someone less familiar with Pfsense will likely spend a lot of time trying to hunt why their IPv6 is nto working. The user interface should probably warn the user and not allow such a configuration to be saved in the first place (just like it is being done when the Default valid lifetime is set to below 7200)

Thanks!
