2 connections with two different ISP

Hi all,

I have 4 computers in LAN (on switch), and i have two ADSL lines from two different ISP.
First: I want to share these two connections between 4 computers in my network (i want bandwidth from this two ADSL lines to share in local network).
Second:And also can i do some restrictions with router os, i have a little sister and i want to restrict her facebook, myspace etc, until 16:00 hours?
I found some tutorials on wiki page:
http://wiki.mikrotik.com/wiki/Load_Balancing_Persistent
http://wiki.mikrotik.com/wiki/Load_Balancing
Which should i follow for my first question?
Here is my current network:
ADSL line to D-LINK router (DIR-100) (with 4 port switcher inside), 4 computers on this 4 ports (with local static addresses).
Now i got second ADSL line, i was thinking to change this dlink with router OS, and one 8-port switch.
Is this plan OK?

Thanks
Best Regards
Mark

Can somebody Help? :question:

Please

Load_Balancing_Persistent is better and less trouble.

yes Load_Balancing_Persistent shoud be used to avoid weird disconnects etc.

for blocking addresses like you mentioned you can use /ip webproxy that and scheduler to enable and disable rules you set to limit access times.

here is link to manual:
http://www.mikrotik.com/testdocs/ros/3.0/pnp/proxy.php

read about access list and how to set up transparent proxy, also, you do not have to enable actual proxying so no cache is saved on router, so you will use it just as address filter.
