Abstract
Lately, the use of the NAT has become unavoidable with the increase of P2P traffic along with the exhaustion of IPv4 IP address. Due to NAT properties, NAT's internal host can only be connected through a relay method using the outside server. Accordingly, there is a lot of resource exhaustion of the relay server on the NAT exterior and network traffic increases. This essay proposes a topology that can form sessions to the NAT interior from the NAT exterior and that will decrease network traffic by placing NAT exterior relay servers in the NAT interior.
