A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

A29J_130789574330391040IMb0cMkpFw.jpgEdge router x by ubnt is a router which is not expensive but is has a lot of advanced futures. It has its down side to it that its GUI is hard to figure out, also vary little documentation available. But once you get to know it there is a lot you can do with it.
What I will be focusing is when having two networks on the router and you want to create a firewall between the two networks. This can be useful for example, where you have one secure network and one that is a not that secure [can be a wireless network, etc.] and you want to protect the secure network from any attack that my come from the not secured network.
A ubnt router could be configured by port, you can have as many networks as the amount of ports on the router (without having a vlan although you can have a vlan as well).
Now Let’s start with a example we have 2 networks one is 192.168.1.1 on eth0 which is not the secure network, and 192.168.2.1 on switch0 which runs on eth2/eth3/eth4/eth5 (eth1 we use for the WAN)  which is the secure network. You also want to restrict the .1.1 from having access to the .2.1 and from accessing the router management.
1-      Create a firewall port group that will include ssh port (22) http (80) https (443) and telnet (23).
2-       Go to the Firewall/NAT tab, firewall/add ruleset, name it, set the default action to accept.
3-      On the newly created ruleset, action/configuration/roles/add new rule, name it, action -drop, next move to advanced, check -established …

Stuck with the router not picking the correct IP of your modem?

Try logging into the router's homepage (normally 192.168.0.1 depending the brand of it), log with administrative accounts and go to WAN connections, release it and renew it..!

If this does not work and the router keeps the same IP even after attempting to renew it, probably the ISP might need to change and release it from the modem or.. you could connect directly to the modem, do an IPCONFIG /RELEASE  ,  IPCONFIG/RENEW, then plug everything back to the router and re-do the first steps again, and maybe just maybe it will change this time.

Good night everyone.

I finally decided to get one of these open source customizeable routers and I'm loving it. It's for advanced consumers and it is a bit pricey but it works well and is really fast.

I was going to order from Amazon but they ran out so I ordered from the same company on eBay. I tried waiting for the higher spec'd one but I couldn't wait any longer. It looks like they're back on Amazon now though.
