OK. So I have now configured Captive Portal for the users on that
network. Works fine as far as captive portal issues go - all blocked
until they agree, and I can configure certain users to bypass the
captive portal. Nice.
Unfortunately, this doesn't address my first concern - the ability to
block certain (or all unspecified) MAC addresses from gaining access to
Unfortunately, it also doesn't address my second concern - the ability
to have the MAC addresses in a list and be able to turn them on/off with
a checkbox. Even in Captive Portal when a MAC is deleted from the
"Pass-through MAC" area, it is deleted, not just disabled.
So, what I'd like to see for the Captive Portal section is the
1. The ability to just disable a particular MAC/IP from being on the
"Pass-Thru" or "Block" list, not having to delete it totally - somewhat
like in the Firewall Rules section where a rule can be configured but
2. The ability to block a particular MAC address in a similar way to
"Pass-through MAC", but called something like "Blocked MAC".
3. Same goes with IP address as well as MAC address.
4. What would be really nice is a checkbox in the "Blocked" sections for
"Block all MACs/IPs not listed in the Pass-Thru Section" which would be
a really, really quick and dirty "close" of the network to all non-admin
(or whoever's allowed to pass thru) users.
Unfortunately, many of the tennants aren't sheep, so they can configure
IPs and MACs to get around simple blocks. Hence why the "Blocked MACs"
and "Blocked IPs" would be nice.
