help

Good afternoon,
I have a rb951g-2hnd router, I want to have two wan, does it work?
I want to use it as an antivirus, does it work?
I want to back up the network, does it work?
I want to have internet content control, does it work?
So how do you restrict internet sites, does it work?

Can advise me by telling me if this equipment does that, or I get a more robust microtick and if so, can you recommend a model that does that?

thank you

At first read tthe documentation
http://wiki.mikrotik.com/wiki/Manual:RouterOS_FAQ

Yes

I want to use it as an antivirus, does it work?

No

I want to back up the network, does it work?

??? Please explain what You mean by this

I want to have internet content control, does it work?

Somehow Yes, but better to use proxy or specialized content filters

Can advise me by telling me if this equipment does that, or I get a more robust microtick and if so, can you recommend a model that does that?

All these are RouterOS features, not hardware features.
