How i migrated my TS3 server to new host

gistfile1.txt

# i run this on my current TS3 server to redirect connections on new host
# --to might be changed to --to-destination
# %%DESRINATION.IP%% is ip address of my new VDS

iptables -t nat -A PREROUTING -p tcp --dport 9987 -j DNAT --to %%DESRINATION.IP%%:9987
iptables -A FORWARD -d %%DESRINATION.IP%% -p tcp --dport 9987 -j ACCEPT

# and for UDP, not sure if TCP port even matter for TS3

iptables -t nat -A PREROUTING -p udp --dport 9987 -j DNAT --to %%DESRINATION.IP%%:9987
iptables -A FORWARD -d %%DESRINATION.IP%% -p udp --dport 9987 -j ACCEPT

iptables -t nat -A POSTROUTING -j MASQUERADE
sysctl net.ipv4.ip_forward=1
