I have a pfSense virtual appliance set up in front of a Windows server. The pfSense appliance has been configured with two L2L IPSec VPN sites and not too much else. The appliance has two vNics which both exist on the same VLAN, but one is "WAN" and the other is "LAN."
When I run speedtest.net on my Windows server when I have configured it to use a static WAN address and gateway, I get great speeds - maybe around 50 down, 15 up. However, when I configure it with a private IP address, I get similar download speeds but terrible upload speeds - around 2 or 3 Mbps consistently. I used Wireshark to see what gives but there didn't appear to be too much helpful information there, or I just could not find it.
Besides the L2L VPNs, other configurations include:
- Automatic Outbound NAT
- Virtual P-ARP IP for the Windows Server
- WAN Firewall rule to allow * to * on RDP
- WAN Firewall rule to allow * to * (enabled this just for testing... didn't help!)
- No DHCP or any other services besides IPSec VPN
- No Errors LAN or WAN
- No collisions LAN or WAN
I would be happy to post the full config file if it would help. I've been scratching my head at this one all day!
