Super Slow Download Speed with pfSense in AWS (using AWS Marketplace Image)



  • Hi Everyone,

    I have stood up a pfsense as our vpn concentration for our AWS env with almost all default settings. No traffic shaper enabled...so I'm kinda at a lost.

    From new AWS vpn:

    Testing from Amazon.com (3.208.38.204)...

    On the pfsense box with fetch

    [2.4.4-RELEASE][admin@vpn.corp.40i.fi]/root: fetch -o /dev/null http://download.thinkbroadband.com/100MB.zip
    /dev/null                                     100% of  100 MB 8856 kBps 00m12s
    [2.4.4-RELEASE][admin@vpn.corp.40i.fi]/root: 
     
    

    Also to add, this is openvpn over tcp. If I switch over to using UDP ipv4 only
    I get a slightly better connection
