Natting peer to peer traffic .

Unanswered Question
Nov 24th, 2008

Hi all,

I've 2 gateways ( 2 different ISPs) and different ip address. Therefore I'm natting based on the destination traffic. Recently I tried to put peer to peer traffic via one gateway (natting based on protocol bittorrent,etc ) . But it doesn't work, download speed went down to 2 kbps

Anybody advice on this, how to get this done. this is basic config.


class-map match-any p2p

match protocol bittorrent

match protocol kazaa2

match protocol gnutella


policy-map p2p_mark

class p2p

set dscp 5



interface FastEthernet0/1

service-policy input p2p_mark

ip policy route-map to-2nd_ISP


access-list 102 permit ip x.x.x.x 0.0.0.15 any dscp 5


ip nat inside source list 102 pool 2nd_isp overload


route-map to-2nd_ISP permit 10

match ip address 102

set ip next-hop xxx.xxx.xxx.xxx
