What is the best way to forward a port range to internal ip address and don't lose the router internet access?


My situation:


I've a SHDSL connection with 878 (IOS version 12.4) and one public IP.


If I configure:


"ip nat inside source static <private ip> <public ip> route-map VOIP extendable" to do a port range forwarding, the router lost the internet access due to all outside requests are mapped to internal server ip.


What is the correct way?


Thanks and best regards,


Olaf

you can use TCP ports but it may not work if you are trying to do it for VoIP as it uses some random range of UDP ports


"ip nat inside source static tcp route-map VOIP extendable

The port range is always the same: UDP (10001-20000).


I don't understand "ip nat inside source static tcp route-map VOIP extendable", where is the range? is one port, isn't it?


Best regards,
