Routing in cisco 2620

hello everybody,

I have an easy question:

I want to reroute some voip packet from one router to another,

knowing all source IP , my IP an the destination IP.

In fact I want to receive some voip packet some a customer and send them to my provider in the other side of the worl, without leting the custumer know the final ip. I defenetly sure this must be easy to configure in a cisco router.

thankx for your help

Re: Routing in cisco 2620

you have to explain to us what you want to do in terms of IP address.

The other end of the world does not mean anything to a router.

So, if you want to change the destination address, you will have to do NAT.

That is the only solution.

If you want to route based on source ip and protocol type or ToS (ie Voip), you need policy based routing.

Finally, when playing with VoIP you have to be carefull where you send the packets since transport time must be less than 175 ms (+/-) if you want to avoid poor performance.
