Lan & Wan Server Solution !

[ps2silver]

Hi !

I'm behind a proxy (squid) and a firewall (iptables) but it's impossible to me launch a wan server sucessfully,otherwise i can play on lan with the server (srcds) .

These are my iptables rules:

$IPTABLES -A PREROUTING -t nat -p udp -i $INET_IFACE --dport $HL2_PORT -j DNAT --to $HL2_SERVER:$HL2_PORT
$IPTABLES -A FORWARD -i $INET_IFACE --out-interface $LAN_IFACE -d $HL2_SERVER -p udp --dport $HL2_PORT -j tcp_allowed
$IPTABLES -A PREROUTING -t nat -p udp -i $INET_IFACE --dport 27020 -j DNAT --to $HL2_SERVER:27020
$IPTABLES -A FORWARD -i $INET_IFACE --out-interface $LAN_IFACE -d $HL2_SERVER -p udp --dport 27020 -j tcp_allowed
$IPTABLES -A PREROUTING -t nat -p tcp -i $INET_IFACE --dport $HL2_PORT -j DNAT --to $HL2_SERVER:$HL2_PORT
$IPTABLES -A FORWARD -i $INET_IFACE --out-interface $LAN_IFACE -d $HL2_SERVER -p tcp --dport $HL2_PORT -j tcp_allowed

Where HL2_SERVER is the internal ip 192.168.x.x and HL2_PORT is 27015,the default port.

I launch the server with the next params:

./srcds_run -console -game cstrike +ip 192.68.x.x -p 27015 +map de_aztec +maxplayers 16 -debug

It seems the problem comes from proxy,but not sure xD

The operative system is Debian sarge

Thx very much

I've resolved the problem

The complete iptables rules are:

HL2_SERVER="192.68.x.x"
HL2_PORT="27015"
GAMESPORTS="27000:27030"
INET_IFACE="EXTERNAL IP"
LAN_IFACE="INTERNAL IP"

$IPTABLES -A INPUT -i $INET_IFACE -p tcp -d $HL2_SERVER --dport $HL2_PORT -s $ANYWHERE --sport $GAMESPORTS -j ACCEPT
$IPTABLES -A INPUT -i $INET_IFACE -p tcp -d $HL2_SERVER --dport $HL2_PORT -s $ANYWHERE --sport $GAMESPORTS -j ACCEPT
$IPTABLES -A FORWARD -i $INET_IFACE -p udp -d $LAN_IP_RANGE --dport $HL2_PORT -s $ANYWHERE --sport $GAMESPORTS -j ACCEPT
$IPTABLES -A PREROUTING -t nat -p udp -i $INET_IFACE --dport $HL2_PORT -j DNAT --to $HL2_SERVER:$HL2_PORT
$IPTABLES -A FORWARD -i $INET_IFACE -o $LAN_IFACE -d $HL2_SERVER -p udp --dport $HL2_PORT -j tcp_allowed


I hope this help someone too

Hello mate, im having the same problem but with xp pro dedicated server. Is there an ip table thingy in windows. where is it?
Any how you ve given me a kick in the right direction me thinks.

back to google!

[popa]

lol there is no 'ip tables thingy' for windows. give us some info on what version of windows you are using

[mrclunk]

yeah i relise that now, thanks anyway. iptables are part of linux firewall configs. I think ive cracked the problem now. I didnt realise before that u carnt see a dedicated server on ur own network with the server browser in cs (on a different pc in the network), you have to manually enter your ip address into favorites to be able to see it. For anyone else reading this dont bother putting the "+ip ***.***.***.***" business in your srdc.exe shortcut if your running the server on a network behind a nat router. If youve forwarded the ports correctly srcds seems to detect the local ip address.
note: im new to this so i could be very very wrong.
