[Solved] Installed a new Intel PWLA8391GT PCI NIC ($33.00). Re-installed Feb 16 Beta 2.0 build and configured for VLAN's. Now getting 70 mbps sustained from Server -> Cisco 3750 (100 meg) -> Cisco 3550 (100 meg)-> pfSense (100 meg) OPT1 VLAN100 on 3550 -> Server on OPT2 VLAN200 on 3550
Did not need to add any tweaks to advanced settings and here is the Cisco config for those interested:
Cisco 3550 (Old ass switch)
interface FastEthernet0/1
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,100,200,300,400,1001-1005
switchport mode trunk
switchport nonegotiate
spanning-tree portfast trunk
spanning-tree bpdufilter enable
This switch config provides the cleanest and fast re-converge time.
Peace,
