Hi, I have 2 PC in a LAN connected to an internet gateway (ADSL). My bnetd server is on the gateway. All connections are OK but there is a big pb : it is very slow. The computers are goods and the connections too. I think it is a pb in my iptables rules. I join my script, could tell me what is wrong ?
note : if you have the same architecture than me, you can use that script but it is slow :o( #!/bin/sh iptables -t nat --flush modprobe iptable_filter modprobe iptable_nat modprobe ipt_MASQUERADE iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE # Activate forwarding echo "1" > /proc/sys/net/ipv4/ip_forward # variables GTW_EXT=217.128.99.54 GTW_INT=10.0.0.2 # inside iptables -A PREROUTING -t nat -d $GTW_EXT -j DNAT --to-destination $GTW_INT # outgoing for i in 1 3 4 5 do iptables -A POSTROUTING -t nat -s 10.0.0.$i --protocol udp --destination-port 6112 -j SNAT --to-source $GTW_EXT:888$i iptables -A POSTROUTING -t nat -s 10.0.0.$i --protocol tcp --destination-port 6112 -j SNAT --to-source $GTW_EXT:888$i done # incoming for i in 1 3 4 5 do iptables -A PREROUTING -t nat -d $GTW_INT --protocol udp --destination-port 888$i -j DNAT --to-destination 10.0.0.$i:6112 iptables -A PREROUTING -t nat -d $GTW_INT --protocol tcp --destination-port 888$i -j DNAT --to-destination 10.0.0.$i:6112 iptables -A OUTPUT -t nat -d $GTW_INT --protocol udp --destination-port 888$i -j DNAT --to-destination 10.0.0.$i:6112 iptables -A OUTPUT -t nat -d $GTW_INT --protocol tcp --destination-port 888$i -j DNAT --to-destination 10.0.0.$i:6112 done # update bnetd gametrans file echo "" > /usr/local/etc/gametrans for i in 1 2 3 4 5 do echo ": 10.0.0.$i $GTW_EXT:888$i 10.0.0.0/24 " >> /usr/local/etc/gametrans done # display LOGS echo "=============================" cat /usr/local/etc/gametrans echo "=============================" iptables -L -v -t nat
