Problem with MSN Messenger Voice Chat and ICQ Voice Chat.
My situation is:
_____ _____________ ____ _______________________
| | |in eth0 (RealIP)| | | |
|
| ISP |-->| Slackware |-->| HUB|-->| LOCAL AREA (6 Computers)|
| | | 9.0 | | | | 10.0.0.2 -
10.0.0.7 |
| | |out eth1 (Local)| | | |
|
| | | 10.0.0.1 | | | |
|
-------- ----------------------- --------
------------------------------------------
My ISP give me 13 Real-IPs. 1st Real-IP (80.xxx.xxx.xx1) is on the eth0
adapter on Linux Slackware machine. All other Real-IPs are on the virtual
eth0:1, eth0:2, eth0:3 etc.
eth1 is my other adapter with first local IP.
I uses iptables to make the nat for Local Area.
My iptables are:
/usr/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.2 -o eth0 -j SNAT --to
80.xxx.xxx.xx2
/usr/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.3 -o eth0 -j SNAT --to
80.xxx.xxx.xx3
/usr/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.4 -o eth0 -j SNAT --to
80.xxx.xxx.xx4
/usr/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.5 -o eth0 -j SNAT --to
80.xxx.xxx.xx5
/usr/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.6 -o eth0 -j SNAT --to
80.xxx.xxx.xx6
/usr/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.7 -o eth0 -j SNAT --to
80.xxx.xxx.xx7
/usr/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.8 -o eth0 -j SNAT --to
80.xxx.xxx.xx8
/usr/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.9 -o eth0 -j SNAT --to
80.xxx.xxx.xx9
/usr/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.10 -o eth0 -j SNAT --to
80.xxx.xxx.x10
/usr/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.11 -o eth0 -j SNAT --to
80.xxx.xxx.x11
/usr/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.12 -o eth0 -j SNAT --to
80.xxx.xxx.x12
/usr/sbin/iptables -t nat -A POSTROUTING -s 10.0.0.13 -o eth0 -j SNAT --to
80.xxx.xxx.x13
All of this working fine, but I can't establish Voice connection with MSN
Messenger and ICQ.
Local Area computers working with WindowsXP Pro. They uses my Linux machine
for Gateway and DNS Server.
I can make voice connection with MSN Messenger only on my local area. For
example 10.0.0.2 MSN Messenger Voice Chat to 10.0.0.5 MSN Messenger Voice
Chat.
Thank you in advance.
Julian
