SG-2220 PS4



  • So I have a SG-2220 that I am trying to help troubleshoot. Every device connected except the PS4's has a fantastic connection no issues and great speed. However the PS4s can not download from PSN. The connection will spike, stall, and the drop.

    I am running a home built pfsense box and I have none of these problems. Is there something going on in the SG-2220 that is causing it to drop these connections?

    I have been throwing all my networking know how and experience with pfsense at the problem and I have hit a wall.



  • PSN is notoriously slow. Sometimes it downloads better on rest mode.



  • I've been trying to figure it out and feel like it is either something with his ISP or the PSN server he is hitting from his house. It's just so weird because all of his other devices work great; gaming he has low pings and little lag.

    He is so frustrated with not being able to download he is buying an ASUS router to replace the SG-2220. I honestly can not figure out what is going on or what I can do to try and correct it.



  • Try having them set the PS4 to a static IP while wired, and port forward the following to it:

    TCP: 80, 443, 3478, 3479, 3480
    UDP: 3478, 3479

    Also, enable UPnP and Nat-PMP in the services menu.

    PSN sometimes gets cranky when it detects a possible "strict nat" type, and pfsense will always show a type 3 strict nat until the forwarding is done and you make sure UPNP is enabled and can function. If they have a web server running, you can leave off 80 and 443 from forwarding to the PS4.

    I have set it up with a static NAT, uPNP. Haven't forwarded the ports yet.

    Side note I am seeing a lot of duplicate packets, TCP out of order packets, and retransmission packets. I am going to attach a packet capture that I have scrubbed to only show PSN related traffic. Could someone take a look at this and let me know what they they think?

    I am wondering these packets are causing state issues in pf. TCP out of order from what I can tell points to an Asymmetric routing happening outside his network.
