HTTP and RDP lose connection on and off.



  • Hello

    I have a bit of an issue with RDP clients and HTTP sites that keep dropping their connection.

    I am using 2 x Dl180 G6 thatI have installed pfsense version 2.0.1 (amd64) Connected to a dell powerconnect 5448

    I've attached an image of the setup.

    I have 2 V Lans for each of the WAN groups that are connected to the switch.
    I have 2 WAN ports (WAN1A + WAN1B) a LAN port and a Sync port. Each of the WAN interfaces is connected to an internet provider and has an external ip range of:  94.xxx.xxx.96/27 and 109.xxx.xxx.128/27.

    My NAT rule looks like this: interface: WAN1A, Destination: 94.xxx.xxx.102 , Destination port range: MS RDP to and from, Redirect target IP: 192.168.1.20, redirect target port: MS RDP. Filter rule: Rule NAT.

    I added a VIP type” P ARP” under IP addresses I created a network type 94.xxx.xxx.96/27. I’m not sure if that’s the correct way to do it or If I should have done one IP at a time.
    Anyway after that I can create an RDP connection but if times out after 2-5 min.
    The same issue happens when I create a rule for http. The webpage seems to drop connection for a while.

    I had read that some people have experienced something like this error and had enabled “static route filtering” under “System: Advanced: Firewall and NAT” but that didn’t help.

  • Are you using load balancing on your WAN ports?  Did you enable sticky connections?



  • Yes and yes.



  • Under System -> Advanced -> Firewall/NAT Try playing with the "Firewall Optimization Options" and see if it changes.



  • Ill give it a try and let you know what happens.
