Mumpung ketemu contoh pf untuk warnet ini saya post kan lagi disini

Seperti biasa tolong jangan asal copy paste.. Periksa dan sesuaikan config tersebut dengan keperluan anda.

### macros
# internal and external interfaces (ketikan 'ifconfig' buat lihat interface)
int_if = "vr0"
ext_if = "rl0"  

# Port Yang Boleh Diakses dari Luar Box silahkan sesuaikan  

tcp_services = "{ 80, 110, 25, 53, 113, 21}"
udp_services = "{ 53, 1194 }"  

# ping requests
icmp_types = "echoreq"  

# Private Network, Yg Mau di Blok Traffiknya
priv_nets = "{ 127.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12, 10.0.0.0/8 }"  

### options
set block-policy return
set loginterface $ext_if
set skip on lo0  

### Scrub
scrub in all  

### nat/rdr
# NAT traffic dari Internal Ke External
nat on $ext_if from $int_if:network to any -> ($ext_if)  

# Port Redirector untuk Transparent Proxy & Transparent FTP
rdr on $int_if proto tcp from any to any port 21 -> 127.0.0.1 port 8021
rdr on $int_if proto tcp from any to any port 80 -> 127.0.0.1 port 3128  

### filter rules
block all  

# Blok Traffik Dari Luar Yang Pake IP Private
block drop in quick on $ext_if from $priv_nets to any  

# Blok Trafik dari Luar ke Internal
block drop out quick on $ext_if from any to $priv_nets  

# Perbolehkan Akses ke TCP port tertentu
pass in on $ext_if inet proto tcp from any to ($ext_if) port $tcp_services flags S/SA keep state  

# Perbolehkan Akses ke UDP port tertentu
pass in on $ext_if proto udp to any port $udp_services keep state  

# Perbolehkan Akses FTP
pass in on $ext_if inet proto tcp from port 20 to ($ext_if) user proxy flags S/SA keep state  

# Ping Reply OK
pass in inet proto icmp all icmp-type $icmp_types keep state  

# Perbolehkan Traffik dari Internal ke Internal Interface
pass in  on $int_if from $int_if:network to any keep state
pass out on $int_if from any to $int_if:network keep state  

# Perbolehkan Traffik keluar melalui External Interface
pass out on $ext_if proto tcp all modulate state flags S/SA
pass out on $ext_if proto { udp, icmp } all keep state
