you have no idea what ur talking about do you. ya cant make a lag switch by blocking ports lol got to the lag switch tut on how to make it

wtf are you on? ARE YOU CRAZY please tell me where the hell you got that

You can actually, connecting to game servers uses ports, same as any other server. You will need to find out the port in which PSN uses. You could Google PS3 ports and find something I'm sure, if not PM Sony. Blocking a port will cease connection, therefor give LAG. With a lag switch all you doing is stopping a connection, which is the same as this guy asks.

You could always use this if you're not doing PS3 or XBOX360.

You must login or register to view this content.

this guy speaks the truth.

So you'r telling me this kid is going to over and over open and close his ports for lag?

Well I suppose it's much more work in a way, but if the guy can't afford to tear open his Ethernet cable, I'm sure this way sounds very likable to him .

The guy may have Linux, so here is a little firewall script for a router.

    <<<@!1!@>>>

#!/bin/sh

# squid server IP

SQUID_SERVER="192.168.0.11"

# Interface connected to Internet

INTERNET="eth0"

# Interface connected to LAN

LAN_IN="eth1"

# Squid port

SQUID_PORT="3128"

# DO NOT MODIFY BELOW

# Clean old firewall

iptables -F

iptables -X

iptables -t nat -F

iptables -t nat -X

iptables -t mangle -F

iptables -t mangle -X

# Load IPTABLES modules for NAT and IP conntrack support

modprobe ip_conntrack

modprobe ip_conntrack_ftp

# For win xp ftp client

#modprobe ip_nat_ftp

echo 1 > /proc/sys/net/ipv4/ip_forward

# Setting default filter policy

iptables -P INPUT DROP

iptables -P OUTPUT ACCEPT

# Unlimited access to loop back

iptables -A INPUT -i lo -j ACCEPT

iptables -A OUTPUT -o lo -j ACCEPT

# Allow UDP, DNS and Passive FTP

iptables -A INPUT -i $INTERNET -m state --state ESTABLISHED,RELATED -j ACCEPT

# set this system as a router for Rest of LAN

iptables --table nat --append POSTROUTING --out-interface $INTERNET -j MASQUERADE

iptables --append FORWARD --in-interface $LAN_IN -j ACCEPT

# unlimited access to LAN

iptables -A INPUT -i $LAN_IN -j ACCEPT

iptables -A OUTPUT -o $LAN_IN -j ACCEPT

# DNAT port 80 request comming from LAN systems to squid 3128 ($SQUID_PORT) aka transparent proxy

iptables -t nat -A PREROUTING -i $LAN_IN -p tcp --dport 80 -j DNAT --to $SQUID_SERVER:$SQUID_PORT

# if it is same system

iptables -t nat -A PREROUTING -i $INTERNET -p tcp --dport 80 -j REDIRECT --to-port $SQUID_PORT

# DROP everything and Log it

#iptables -A INPUT -j LOG

iptables -A INPUT -j DROP

This should block all connections to any destination from all ports, except 80 which is web browsing. You could make a batch file, with this.
