Re: Mikrotik RouterBoard 1200 support spam blocker or not?

You can block spammer based on IP/port filter rules or you can "play" with
/ip firewall layer7-protocol http://wiki.mikrotik.com/wiki/Manual:IP/Firewall/L7
and, maybe, some scripts.

Re: Building secure firewall

Do you understand differences in chains (input,forward)?
There are many unnecessary rules. 19? 20? 21? 22?
Maybe better accept access for ssh or icmp or another services from trusted network?
Try to disable unused services in "/ip service".

Re: hardware for fast 2km ptp link 2ghz

You don't need 24dB or more antena gain.
You need antena which give you -70..-60 dBm signal strength for maximum channel speed (802.11A - 54M, 802.11N - 150M or 300M).
And don't forget about Fresnel zone if you need maximum throughput.

Re: Clients Disconnect after inserting a new mac in Access L

Not only MAC should be added.
If you add new record and firstly add comment then record will be added with blank MAC and clients will reconnect.
So add MAC and interface/forward/... first.

Re: Hotspot is marked as invalid

If you have added interface to bridge then you must operate with bridge interface and setup Hotspot on bridge interface.
IP address must be assigned to bridge too.
Otherwise use regular interface (wlan1?).

VARELA, looks like you are using MAC address to connect. This is a very slow and unreliable method of communication, and many items are loaded slowly.

Use IP address and check if you have the same problem.
