Pc in the office usually has the old become obsolete even in almost every office Pc are not operated .it is still a PC can be used as a gateway server.In this writen, Here I recount my experience, the PC specification that I use the following :
Processor-Intel pentium II 400 Mhz
-BX Mainboard Intel 440 chipset
-Ram 128 Mb
-Hard disk 3.2-Gb
-Lan-card Realtek RTL8139 (2 pcs)
-CDrom
In this case I use Mikrotik v2.9.7
The first we do is to set up a PC that is working well.
then we install the software on the Pc we have to prepare.
Mikrotik is not free software, we have to buy the license.Free trial is only 24 hours and we can download them in www.mikrotik.com.
Here,I make a Mikrotik installation via console:
Mikrotik v2.7.9
login: admin
password:
First set interface
admin @ Mikrotik> interface print
# Type name Rx-Tx-rate rate MTU
0 R ether1 ether 0 0 1500
1 R ether2 ether 0 0 1500
Provide IP address
admin @ Mikrotik> ip address add address = 192.168.0.1 netmask = 255.255.255.0 interface = ethre1
admin @ Mikrotik> ip address add address = 192.168.1.1 netmask = 255.255.255.0 interface = ethre2
view ip configuration
admin @ Mikrotik> ip address print
Flags: X-disabled, I-invalid, D-dynamic
# Broadcast address network interface
0 192.168.0.1/24 192.168.0.0 192.168.0.63 ether1
1 192.168.1.1/24 192.168.1.0 192.168.0.255 ether2
Provide the gateway
admin @ Mikrotik> / ip route add gateway = 192.168.0.254
see routing
admin @ Mikrotik> ip address print
Flags: X-disabled, the A-active, dynamic D-, C-connect, S-static, rip, r, b-bgp, o-ospf
# DST-address interface Prefsrc Distance Gateway
0 ADC 192.168.1.0/24 192.168.1.1 ether2
1 ADC 192.168.0.0/24 192.168.0.1 ether1
2 AS 0.0.0.0 / 0 r 192.168.0.254
To ensure the configuration is correct try to ping the gateway
admin @ Mikrotik> ping 192.168.0.254
192.168.0.254 64 byte ping: TTL = 64 time <1 ms
192.168.0.254 64 byte ping: TTL = 64 time <1 ms
192.168.0.254 64 byte ping: TTL = 64 time <1 ms
192.168.0.254 64 byte ping: TTL = 64 time <1 ms
2 packets transmitted, 2 packets received, 0% packet loss
round-trip min / avg / max = 0/0.0/0 ms
Then set up DNS, eg as we enter the dns telkomspeedy
admin @ Mikrotik> ip dns set primary-dns = 203.130.206.250 allow-remote-requests = no
admin @ Mikrotik> ip dns set secondary-dns = 202.130.196.5 allow-remote-requests = no
Check the DNS configuration
admin @ Mikrotik> print ip dns
primary-dns: 203.130.206.250
secondary-dns: 202.130.196.5
allow-remote-requests: no
cache-size: 2048Kib
cache-max-TTL: 1W
cache-used: 16KiB
Set up Masquerade
admin @ Mikrotik> / ip firewall nat add action + Masquerade out-interface = ether1
chain: srcnat
Check the configuration Masquerade
admin @ Mikrotik> ip firewall nat print
Flags: X-disabled, I-invalid, D-dynamic
0 chain = srcnat out-interface = ether1 action = Masquerade
Create IP address pool
admin @ Mikrotik> / ip pool add name = dhcp-pool = 192.168.1.1-192.168.1.20 Ranges
Adding DHCPnetwork and gateway
admin @ Mikrotik> / ip dhcp-server network add address = 192.168.1.0/24 gateway = 192.168.1.1
Adding a DHCP server on interface ether2
admin @ Mikrotik> / ip dhcp-server add interface = ether2 address-pool = dhcp-pool
See dhcp server status
admin @ Mikrotik> ip dhcp-server print
Flags: X-disabled, I-invalid
# Name Address Interface Relay pool-Lease-Time Add-ARP
0 x dhcp1 ether2
if we see the dhcp server still have a sign (X) to be made then enable
admin @ Mikrotik> ip dhcp-server enable 0
Thus set up Mikrotik I create as a gateway server and I have applied in My internet cafe and I have also in other places
survivors try "do not chase wasted your old PC"
And do not install this system on the mainboard socket LGA

check before paying
found many cases of incidents that have been in the goods purchased can not be returned again.
This occurred in one of my friend who bought the device in a computer store in the MEDAN.
At first my friend there to check the price before buying a product here that he was looking for and finally have supplyer who sell their products with the cheapest price from a few supplyer and there were other transactions for the purchase of parts for 15 units of computers. but what happens after the check was made out of some products there is a defect. and my friend's party on the protest supplyer the warehouse but they think they have to check the goods carefully and send in the goods in good condition and there is not good communication.
so in this case we can take its wisdom "Purchase price of the goods in accordance with market prices and not obsessed with price and seek supplyer has a good image and then check that the goods are to be witnessed by the supplyer."
And by the way, was not only my friends are victims of supplyer, the fact that many are injured by their product and the fact that they are selling low end products

for it dvdrom we can choose the pioneer but the price is still quite expensive so a cheaper alternatip we can use the Asus, LG, Samsung.
Casing for the recommended power supply with 450 watts.

Selecting the worst.
In the history of the election this time as the election result in the most problem.The first, we already see that is not correct, the determination of changes in election day, determining the number of participants that the selection is very slow, the list of voters who remain perplexed.
In this case is actually a lot of lessons learned by us from all these problems, we can take a decision, that many of them do not reflect the nature of big soulless. did not recognize the error and error is always throw it against the other.
Political money
Artist easily register as a candidate in the party legeslatif certain "they have money."
This is an example of political education is very low, they can cause to the high social envy because they are not through the party cadres.
supervision of the election that bad
implementation of the election unfair and control mechanism that is not good, why?
* The election supervisor who is not strong.
* Supervisors election not so in the respect by each party
