    @microserfs and what IP was that - clearly your current IPv6 address is not block that I show you connected with.. And the only other IPv4 I see you using is not blocked.. You would have to let me know what IP you were coming from that was blocked.. Send it to me via PM if you don't want to make it public.

    Name it "run.sh", copy to pf and chmod according documentation
    https://docs.netgate.com/pfsense/en/latest/development/boot-commands.html#shell-script-option
    You will see messages in the system log like those quoted in the script after logger command.

    @thomaslsmith:

    sounds cool. I wonder if it works like a normal router when I am done with it

    No. It works better.  8)

    the article doesn't say anything about other Atom lines, or the future replacements for Rangeley, either.

    I can't say what I know (CNDA), but Sofia, especially, looks like it was an Intel "science project" from here.

    Amazing how culture can affect business, but it's hard to tell since we're all submersed in culture.

    That or cygwin, msys, etc…

    The windows command prompt "terminal" itself sucks most though. Cygwin with mintty is much, much, much better to deal with than a standard cmd.exe window that has better commands...

    Netgear was launching at the CeBit 2016 their first 802.3bz or NBase-T Switch, called M4200 series
    and later this year Q2 or Q3 they are going to launch the WLAN AP named WNDAP740 that is coming
    also together with this NBase-T ports. Would be nice to get better wireless ac performance.
    Core Switch for routing:
    M7300 + Layer3 license - Bigger Core Switch
    fully Layer3 routing static or dynamic (RIP,OSPF,VRRP,ECMP,ProxyARP,Multinetting)
    M4300 - smaller Core Switch
    fully Layer3 routing static or dynamic (VRRP,HRSP, RIP, OSPF, PIM, PBR)
    NBase-T:
    M4200 Layer2+, NBase-T Switch for Wave2 11ac wireless access points
    8 x 2,5 GBit/s PoE+ Ports
    2 x 5,0 GBit/s (Combo Ports 2,5 GBit/s or 5,0 GBit/s)
    2 x SFP+ 10 GBit/s Slots

    @Harvy66:

    There are a few possibilities that can explain what you saw

    University was doing something similar to pfBlockerNG v2.0

    In order to block ads by inspecting the traffic, you have to man in the middle HTTPS. This may be the lesser of evils in some cases, but it is something very important to think about.

    Just as a note, pfBlockerNG, is not really MITM for HTTPS. It would be more DNS sinkholing then anything. MITM is evil, and should never be done for content filtering… :)

    The default gateway target, which seems to be a DHCP server in my ISP

    While I didn't wireshark it this time, I have done so in the past. What I saw was a bunch of dup packet responses getting sent from my WAN. WAN ingress was 100Mb/s and LAN egress was about 70Mb/s. PFSense seems to have filtered out the already acknowledged traffic and responded on behalf of my computer. When I did a trace route to these target IP addresses, while I was still downloading from them, I saw normal 2ms ping here, 10ms ping there, 20ms ping there, then right before it got to the seeder, 2,000+ ms pings. I samples about 10 TCP connections that were causing all of those dup packet responses, and they all had the same large ping jump 1-2 hops away from reaching them, but otherwise good hop pings within their ISP's network. Just not the last 2.

    I do use HFSC and CoDel

    My ISP does also have some unidentified AQM. All I know is without any shaping on my end, DSLReports says I get about 20-30ms of buffer bloat. With shaping on my end, I get bloat down to about 1ms. This is also reflected when I had a DOS volume attack tested against my connection. I had a service send 110Mb/s at my 100Mb connection and I saw about 10% loss and typically 30ms-40ms of latency. Even when pushed to 200Mb flood, still 30ms-40ms, but something like 50%+ loss. I forget exactly how much, but my connection was dead.

    The several crash reports from the IP you sent me are all indicative of a hardware problem.

    Made time to test OpenVPN too.
    These tests where done from client to PFS to client.

    OVPN-Server:
    Remote Access (SSL/TLS+User Auth)
    udp
    tun
    tls static key 2048
    Diffie Hellman 2048
    Certs 2048
    Encryption AES-256-CBC
    Auth digest SHA512
    prng RSA-SHA512 32
    fast-io
    tls-version-min 1.2 or-highest
    No hardware crypto selected
    No compression

    OVPN-Client export:
    dev tun
    persist-tun
    persist-key
    cipher AES-256-CBC
    auth SHA512
    tls-client
    client
    resolv-retry infinite
    remote 192.168.11.200 1194 udp
    lport 0
    verify-x509-name "OVPN-SERVER-CERT" name
    auth-user-pass
    ns-cert-type server
    comp-lzo no
    prng RSA-SHA512 32
    tls-version-min 1.2 or-highest

    Clients connect with:
    Control channel: TLSv1.2 DHE-RSA-AES256-GCM-SHA384 2048 bit RSA

    PFS:
    System/ Advanced/ Miscellaneous - Cryptographic Hardware -> None
    VPN/ OpenVPN/ Servers/ Edit - Inter-client communication -> Allowed

    Command
    :iperf3 -c 10.0.10.3 -t 30

    With above config:
    [ ID] Interval          Transfer    Bandwidth
    [  4]  0.00-30.01  sec  534 MBytes  149 Mbits/sec                  sender
    [  4]  0.00-30.01  sec  534 MBytes  149 Mbits/sec                  receiver

    Above + System/ Advanced/ Miscellaneous - Cryptographic Hardware -> AES-NI:
    [ ID] Interval          Transfer    Bandwidth
    [  4]  0.00-30.01  sec  530 MBytes  148 Mbits/sec                  sender
    [  4]  0.00-30.01  sec  530 MBytes  148 Mbits/sec                  receiver

    Above + OVPN-Server BSD cryptodev engine:
    [ ID] Interval          Transfer    Bandwidth
    [  4]  0.00-30.01  sec  523 MBytes  146 Mbits/sec                  sender
    [  4]  0.00-30.01  sec  523 MBytes  146 Mbits/sec                  receiver

    Above + add to client and server:
    sndbuf 524288
    rcvbuf 524288
    Which gave:
    [ ID] Interval          Transfer    Bandwidth
    [  4]  0.00-30.01  sec  538 MBytes  150 Mbits/sec                  sender
    [  4]  0.00-30.01  sec  538 MBytes  150 Mbits/sec                  receiver

    Above + no encryption
    cipher none
    auth none
    [ ID] Interval          Transfer    Bandwidth
    [  4]  0.00-30.01  sec  967 MBytes  270 Mbits/sec                  sender
    [  4]  0.00-30.01  sec  967 MBytes  270 Mbits/sec                  receiver

    I think the results for encryption and no encryption speak for themself.

    I don`t need big speeds for my home use but if someone has a idea for why enabling/disabling engine makes no difference, i would like to read it.

    What is this setting doing? For what does it apply?
    System/ Advanced/ Miscellaneous - Cryptographic Hardware -> AES-NI
    I did not test with that setting off and enabling only BSD crypto in OpenVPN Server, will do that next time.

    Run Ping Test. From the tools page, select Start, in the Ping Test (Real Time) box. This will advance you to a page indicating that all of the listed servers will be ping-ed twice per second and every thirty (30) seconds a report on your connection from A to F will be provided.

    The Fastirons listed above have been replaced by the Fastiron FCX/SX series (maybe the ICX series as well, I'm more knowledgeable on their current carrier gear than I am edge switching), but expect $3,000 to $4,000 for base models and going up quickly from there. The stuff linked above for 30 bucks went for the same pricing when new years ago - if it makes you feel any better they're still actively updated, the firmware running on my GS was pushed out by brocade just a couple months ago

    This has gotten way off topic and the politics has offended some, ending this thread here.

    Now that's a handy little feature, especially when you go back to a box you've  been messin' with to get the rules right.

    Makes it easy to find all those spurious rules that do nothing at all in the end.

    2.3 is a hit in my books so far, the 12 or so systems I've upgraded so far have been all smooth.

    Kudos for an excellent release  :D
