Possible Bug in the TS3 Server Network Stack (Multiple Interface Environment)

[mschroeder84]

Hello,

i using the TeamSpeak 3 (Version 3.0.5, x86) Server on a Unix System with multiple Network Interfaces.

Example:
ppp0 84.46.32.22 (WAN Interface 1)
ppp1 83.151.26.87 (WAN Interface 2)

Linux Routing Table:
ip route add default dev ppp0 table 10
ip route add default dev ppp1 table 11

Linux Routing Rules
ip rule add from 84.46.32.22 lookup 10
ip rule add from 83.151.26.87 lookup 11


The Problem: Packages who received on ppp1 currently sends out via ppp0

The TeamSpeak 3 Server Listens on 0.0.0.0:9987

I think there is a Bug in the TeamSpeak 3 server at the logic to determinate the Source Address while sending Packages.

Logfile (Input Package):
Jun 26 15:47:43 mx kernel: [275254.011484] IN=ppp1 OUT= MAC= SRC=31.18.155.232 DST=83.151.26.87 LEN=189 TOS=0x00 PREC=0x00 TTL=114 ID=3041 PROTO=UDP SPT=1308 DPT=9987 LEN=169 MARK=0x1

Logfile (Wrong Source Address Response Package):
Jun 26 15:47:43 mx kernel: [275254.060514] IN= OUT=ppp0 SRC=84.46.32.22 DST=31.18.155.232 LEN=213 TOS=0x00 PREC=0x00 TTL=64 ID=0 DF PROTO=UDP SPT=9987 DPT=1308 LEN=193

Wrong 84.46.32.22

Correct 83.151.26.87

This is no bug. The teamspeak server listens on more as 1IP on your server. This does not work, whe nclient askt IP 1 fro server details and IP for the channel and userlist.

Please use the following parameter for your server:

default_voice_port=9987
voice_ip=83.151.26.87 
filetransfer_port=30033
filetransfer_ip=83.151.26.87 
query_port=10011
query_ip=83.151.26.87
