Just fix your hosts file and httpd conf
1. Edit hosts file :
[root@pisangraja ~]# hostname
pisangraja.jc
[root@pisangraja ~]# vi /etc/hosts
::1                     localhost
127.0.0.1               localhost
192.168.12.200          pisangraja
192.168.12.200          pisangraja.jc
2. Edit httpd conf
[root@pisangraja ~]# vi /usr/local/etc/apache22/httpd.conf
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn’t have a registered DNS name, enter its IP address here.
#
ServerName www.pisangraja.jc:80

VPN adalah singkatan dari virtual private network, yaitu jaringan pribadi (bukan untuk akses umum) yang menggunakan medium nonpribadi (misalnya internet) untuk menghubungkan antar remote-site secara aman. Perlu penerapan teknologi tertentu agar walaupun menggunakan medium yang umum, tetapi traffic (lalu lintas) antar remote-site tidak dapat disadap dengan mudah, juga tidak memungkinkan pihak lain untuk menyusupkan traffic yang tidak semestinya ke dalam remote-siteVPN adalah singkatan dari virtual private network, yaitu jaringan pribadi (bukan untuk akses umum) yang menggunakan medium nonpribadi (misalnya internet) untuk menghubungkan antar remote-site secara aman.

10 Langkah Setting Router sederhana menggunakan MikroTik

10 Langkah Setting Router sederhana menggunakan MikroTik

Contoh Kasus :
PC CLient — > Switch –> Router —> Internet

IP PUBLIC : x.y.z.pub/29
DNS : x.y.z.dns1 dan x.y.z.dns2
Gateway : x.y.z.gw
IP address LOCAL ROUTER : 192.168.100.1/24
IP address Client : 192.168.100.2/24

Catatan : Sesuaikan Hardware, IP Address, DNS, Gateway dengan yang anda miliki

Hardware :
Router :  RouterBoard 1000 (Mikrotik v3,19 Stable)

Mikrotik RB1000

Switch : D-Link DES-3026 Ethernet Switch

D-Link DES-3026 Ethernet Switch

PC Client : PowerBook G4

Powerbook G4

Setting ROUTER
1. Ganti default password Mikrotik
[admin@titik.org] > /user set admin password=whatever

2. Rename ethernet name :
[admin@titik.org] > /interface print
Flags: D – dynamic, X – disabled, R – running, S – slave
#     NAME                                              TYPE             MTU
0  R  ether1                                            ether            1500
1     ether2                                            ether            1500
2     ether3                                            ether            1500
3  R  ether4                                            ether            1500
[admin@titik.org] > /interface set ether1 name=IP-LOCAL
[admin@titik.org] > /interface set ether4 name=IP-PUBLIC
[admin@titik.org] > /interface print
Flags: D – dynamic, X – disabled, R – running, S – slave
#     NAME                                              TYPE             MTU
0  R  IP-LOCAL                                          ether            1500
1     ether2                                            ether            1500
2     ether3                                            ether            1500
3  R  IP-PUBLIC                                         ether            1500

3. Setting IP Address
[admin@titik.org] > /ip address add address=x.y.z.pub/29 interface=IP-PUBLIC
[admin@titik.org] > /ip address add address=192.168.100.1/24 interface=IP-LOCAL
[admin@titik.org] > /ip address print
Flags: X – disabled, I – invalid, D – dynamic

1   192.168.100.1/24   192.168.100.0   192.168.100.255 IP-LOCAL

4. Setting Gateway
[admin@titik.org] > /ip route print
Flags: X – disabled, A – active, D – dynamic, C – connect, S – static, r – rip, b – bgp, o – ospf, m – mme,
B – blackhole, U – unreachable, P – prohibit

5. Test Ping Gateway
[admin@titik.org] > /ping x.y.z.gw
x.y.z.gw 64 byte ping: ttl=64 time=1 ms
x.y.z.gw 64 byte ping: ttl=64 time=1 ms
x.y.z.gw 64 byte ping: ttl=64 time=1 ms
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 1/1.0/1 ms

6. Setting DNS
[admin@titik.org] > /ip dns print
primary-dns: 0.0.0.0
secondary-dns: 0.0.0.0
allow-remote-requests: no
max-udp-packet-size: 512
