I am running obsd 5.4 as my NAT router. I decided to setup a second obsd box and run carp between the two for the external NATed interface (facing the ISP). After I setup everything and switched pf to NAT using the address on the carp interface, I'm seeing about 12Mbps - 13Mbps on the download, I have a 60Mbps pipe (down). When I switch pf back to NAT using the address on the physical interface, I get my full 60Mbps. Any ideas as to what I could be doing wrong that would limit performance through the carp interface to around 12Mbps - 13Mbps ?
Thanks ...
