Connect to MSCHARPV2 – WPA – PEAP wireless AP

Edit /etc/wpa_supplicant.conf adding:

network={
 key_mgmt=WPA-EAP
 proto=WPA
 eap=PEAP
 scan_ssid=1
 mode=0
 pairwise=TKIP
 password="password"
 group=TKIP
 identity="DOMAIN\user"
 phase1="peaplabel=0"
 phase2="auth=MSCHARPV2"
 ssid="ap essid"
}

start wpa_supplicant daemon:

# wpa_supplicant -Dwext -iwlanx -c/etc/wpa_supplicant/wpa_supplicant.conf -dd

Then:

# iwconfig wlanx essid "ap essid"
# dhclient wlanx

IPTABLES: mapping ports with DNAT

If you want to redirect the web service for example, from the public IP address to a Private ones (located in your lan with private IP range) you use:

# iptables -t nat -A PREROUTING -p TCP --dport 80 -j DNAT --to-destination 10.10.0.15 (replace with yours)

In this case I’m mapping the Web service from my Public Server to a Private ones.

Note: The Public server can have the port 80 closed in its firewall rules

IPTABLES: basic rules

Nowadays, It’s very important to get a fully working/firewall on your computer or in which you put your hands. I used to use Firestarter in my Debian’s Based System, But although is very functional, I didn’t like the way to apply the rules and manage the FORWARD and OUPUT rules as well. To manage your firewall directly with iptables you can read this and find it out in a simple way.

I supose you already have iptables installed in your system.

Previously to set up rules:

# iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
# iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT
# iptables -A OUTPUT -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT

General Rules:

# iptables -P INPUT DROP
# iptables -P FORWARD DROP
# iptables -P OUTPUT ACCEPT

Examples of rules:

# iptables -A INPUT -d (server address) -p FTP --dport 22 -j ACCEPT
# iptables -A INPUT -s 172.0.0.2 -d (server address) -p ICMP -j ACCEPT
# iptables -A INPUT -d (server address) -p ICMP -j DROP
