[ltp] realplayer stopped working ??

[Bill Barnard]

These are the rules I have on my iptables firewall running on my machine
that connects to the outside world:

###############################################################
# Accessing Real Audio Servers (TCP 7070, 554)
# and incoming ports (UDP 6970 - 7170)

iptables -A FORWARD -i $LAN_INTERFACE -o $INTERNET_INTERFACE -p tcp \
         -s $LAN_ADDRESSES --sport $UNPRIVPORTS \
         --dport 7070 \
         -m state --state NEW -j ACCEPT

iptables -A FORWARD -i $LAN_INTERFACE -o $INTERNET_INTERFACE -p tcp \
         -s $LAN_ADDRESSES --sport $UNPRIVPORTS \
         --dport 554 \
         -m state --state NEW -j ACCEPT

iptables -A INPUT -i $INTERNET_INTERFACE -p udp \
         --sport $UNPRIVPORTS \
         -d $IPADDR --dport 6970:7170 -j ACCEPT

iptables -A FORWARD -i $INTERNET_INTERFACE -o $LAN_INTERFACE -p udp \
         --sport $UNPRIVPORTS \
         -d $LAN_ADDRESSES --dport 6970:7170 -j ACCEPT

Definitions:
INTERNET_INTERFACE="eth0"               # Internet-connected interface
LAN_INTERFACE="eth1"                    # internal LAN interface
$IPADDR="my assigned ip address from my ISP"
$LAN_ADDRESSES="my internal ip address range"
UNPRIVPORTS="1024:65535"                # unprivileged port range

I don't recall why I don't have the stateful firewall rules enabled for
the udp packets - must be that there's no state tracked for udp
connections...

Anyway realplayer works fine for me. Now if only there was something
worth listening to...

Best,

Bill Barnard
