          Do you see any errors with tcpdump, or in the firewall logs? And what about iperf tests?

            I cant se any errors…

            iperf also gets good speed:
            [2.3.2-RELEASE][root@fw-pfSense-01.localdomain]/root: iperf -c ping.online.net
            –----------------------------------------------------------
            Client connecting to ping.online.net, TCP port 5001
            TCP window size: 65.0 KByte (default)

            [  3] local 87.98.128.127 port 5109 connected with 62.210.18.40 port 5001
            [ ID] Interval      Transfer    Bandwidth
            [  3]  0.0-10.0 sec  654 MBytes  548 Mbits/sec

            And from a vm behind pfsense:
            ^Croot@isp1:~# iperf -c ping.online.net
            –----------------------------------------------------------
            Client connecting to ping.online.net, TCP port 5001
            TCP window size: 85.0 KByte (default)

            [  3] local 192.168.99.101 port 45274 connected with 62.210.18.40 port 5001
            [ ID] Interval      Transfer    Bandwidth
            [  3]  0.0-10.0 sec  1.09 GBytes  935 Mbits/sec

            So i get good speed with iperf. but when i try to download http://proof.ovh.net/files/10Gb.dat i get only get between 10 and 100mbit pr sec

                How big is the TCP window size and how big is the MTU during HTTP?

                        Strange, it looks like packets are discarded or the MTU/Window/Fragmentation sizes are all wrong to cause this. Is MTR installed? Try MTR'ing to that DL server. Oh, and if you simply ping for 100 times, how are the latency/drops?

                            Sounds like you may still be having non-ICMP traffic issues, maybe your offloading settings still aren't right. Can you print the ethtool output on the hypervisor side for the VIF's?

                                  Have you tried pfSense 2.4 Beta just to see if the newer FreeBSD base makes a difference?

                                    Trying to set up tomorrow. but do you think it might be a problem with pfSense or configuration error or problem with OVH?

                                      Others have a working setup on OVH, but it's somewhat tricky with FreeBSD on mass-virtualisation, so it could be an issue with the underlying platform. It's hard to say at this point, but everything still points towards packets being discarded.

                                        i am now running on 2.4, was thinking if i should try without xen-tools first and se how that goes.

                                            I have read over the whole internet on guides to get this working.

                                            And almost everywhere i see this lines:

                                            route add -net 2.3.4.254/32 -iface vmx1
                                            route add default 2.3.4.254

                                            I do not use them, i have only added default gateway and activated gateway outside subnet, is this correct?
