Hello MASQ,
I am trying to setup CUseeMe Masquerading on Linux.
I am using 2.2.14 kernel with ip_masq_cuseeme.c (o).
I have a Windows Me client with CUseeMe version 5.0.
I am facing a problem.
After I open the channels view, if I click on a channel name (link), it
starts the download-find address-contacting-connecting sequence. In this it
always stays in the "connecting" state.
The configuration I have used is as follows.
#initialize
EXTIF=eth0
INTIF=eth1
EXTIP=202.56.255.118
INTIP=192.168.20.12
INTNET=192.168.20.0/255.255.255.0
#Input Policy
ipchains -F input
#ipchains -P input REJECT

ipchains -A input -i $EXTIF -s 0.0.0.0/0 -d $EXTIP/32 -j ACCEPT
ipchains -A input -i lo -s 0.0.0.0/0 -d 0.0.0.0/0 -j ACCEPT
#output policy
ipchains -F output
ipchains -P output REJECT
ipchains -A output -i $INTIF -s 0.0.0.0/0 -d $INTNET -j ACCEPT
ipchains -A output -i $EXTIF -s $EXTIP/32 -d 0.0.0.0/0 -j ACCEPT
ipchains -A output -i lo -s 0.0.0.0/0 -d 0.0.0.0/0 -j ACCEPT
#Forward policy
ipchains -F forward
ipchains -P forward DENY
ipchains -A forward -i $EXTIF -s $INTNET -d 0.0.0.0/0 -j MASQ
# To forward incoming CUSeeMe ports
ipmasqadm autofw -A -r udp 7648 7648 -h 192.168.20.15

ipmasqadm autofw -A -d udp 7648 7648
ipmasqadm autofw -A -d udp 7649 7649
ipmasqadm autofw -A -d tcp 7648 7648
ipmasqadm autofw -A -d tcp 7649 7649
#EOF
I tried tcpdump.
I could see the 7648 tcp packets being sent and being replied.
I could also see the 7648 udp packets. BUT THERE WAS NO REPLY FOR THESE
PACKETS.
Can anyone please help me to find out what is the problem?
One more strange thing. If I not down the server dns name from the above
transaction and try the manual dial, it just works fine without any problem.
I saw the udp 7648 packets being replied too.
Hope the people in the list have understood the problem.
Thanks in advance.
Best Regards,
