Poor openvpn speeds on pfsense client, fast with desktop client to same server.
-
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!
