NAT Overloading: Restricting ports to a higher value?
From the below, I've did a NAT overloading (IOS) for traffic going from 126.96.36.199 to 10.22.22.0/24. But having read in some doc that for icmp traffic, PAT will use ports starting from 0, I'm wondering if there's a way to set the port to a higher port value.
From the below debug, it is currently using port 80. Is there any way to restrict the port to a higher number, e.g. 1000+ ?
