Maximum UDP port forward

Unanswered Question
Apr 27th, 2008

I have a Cisco 2801 router with C2801-IPBASE-M IOS. I have already done a lot of port forward. Now if I want to add more udp port forward it give the following error:

Maximum UDP forwarding ports in use

Is there any limitation of UDP port forward? Can it be maximized by changing the router or ios?

I have this problem too.

I am not doing any nat there. We are providing a service for a software which need to be port forward. For each connectivity we need to forward 3 udp port with specific ip helper-address. Now the router is denying to add new portforward.

Fakrul,

There is indeed a hard limit of 200 ports you can configure for UDP flooding.
