      Hello,

      I have pfsense 2.1.5 i386 setup as an openvpn client connecting to a ubuntu openvpn server. I have pfsense setup to route specific traffic on the lan through the vpn link. This is working fine, however the most performance i'm able to push through the VPN link is ~20Mbit. If i connect to the same vpn server with a desktop client (windows or linux) i'm able to push 80-100Mbit/s. CPU usage on my pfsense machine is about 20% on a 1.6Ghz atom soekris net6501-70. The biggest thing i'm not sure about is the NAT outbound rule i created, it was the only way I was able to get traffic to flow and I just guessed. Thanks!

      ubuntu server config:

      port 1197
      proto udp
      dev tun
      ca ca.crt
      cert server.crt
      key server.key  # This file should be kept secret
      dh dh2048.pem
      server 10.9.0.0 255.255.255.0
      ifconfig-pool-persist ipp3.txt
      push "dhcp-option DNS 208.67.222.222"
      push "dhcp-option DNS 208.67.220.220"
      duplicate-cn
      keepalive 10 120
      comp-lzo
      user nobody
      group nogroup
      persist-key
      persist-tun
      status openvpn-status.log
