I found the solution.

Just a pbf for PC A to route for the service used in NAT to VR2's Default gw to ISP2

thanks for your help.

L4 Transporter

*Network topology may change this method

If you can burn another port, put an L3 interface in VR2 on the same subnet as PC-A (or what ever subnet other trust interface is on). In the DST NAT rule create a SRC NAT also for the IP of the new L3 interface. Return traffic will come back there and route out VR2.



there is only 1 interface for VR2

also there is route for pc A's subnet on VR2

Thanks for advice.

eth1/1 vr1 adsl1  dgw  WAN1

eth1/2  vr2 adsl2  dgw  WAN2

eth1/3 LAN  vr1


pbf route eth1/1 to RDP TO PC A


WAN2  WAN2  Dest.nat

so using eth1/4 vr2

wan2 wan2  sourcenat interface eth 1/4  dest.

is that what you mean ?

Yes, if you SNAT ETH1/4 it return traffic will never hit VR1 and there for route back out ISP2.
