No internet access on SG-1100 with a Static Wan address.



  • Hi,

    First time using a SG-1100 and we're having issues getting internet access via static ip. The static address works as we tested it on a custom box using version 2.4.5-1. The main difference I see between the SG and custom built is the Switch ports/Vlans interface and I have zero experience in that section.

    Setup is like so: Modem(bridge mode) to Wan and LAN to Laptop.

    If WAN is set to DHCP then internet is accessible but once its switched to Static it does not get internet. Cannot ping gateway nor 8.8.8.8

    Any help is much appreciated.

    Then your setting it wrong.. IP communication be it gotten via dhcp or static makes no difference. There is an IP and a mask, and gateway... Doesn't matter how that information is gotten on the device.

    A common mistake when users set static is the mask, since it defaults to 32.. So make sure you are properly setting the mask to what the info given to you for your static setup.



  • Double checked and the subnet mask is correct per the info provided by ISP. This configuration was setup on a pfsense that was built using a USB and it works fine. I applied the same configuration on the SG-1100 and it does not work. Wan interface shows green up arrow but I cannot ping gw nor internet.

    That doesn't mean anything... That just means the interface is enbabled, and there is an interface connection.

    If this is a cable modem in front of pfsense - did you reboot the cable modem.. When you changed the device.. Your saying if yous witch the interface to dhcp it works? And what IP does it get - rfc1918 or public, just different than what your putting in for your static settings?

    From a tech point of view be it the settings get their via dhcp or static have nothing to do with anything.. If your saying you put in 1.2.3.4/24 with gaeteway 1.2.3.1 as your gateway works on router A, but when you put in router be and it gets 5.6.7.8/24 with gateway 5.6.7.1 via dhcp and it works... But then you put in 1.2.3.4/24 gateway 1.2.3.1 it doesn't makes NO sense at all.. Unless your isp has a static arp or something setup that 1.2.3.4 has to be a specific mac address.

    Contact your ISP... But the info gotten via dhcp or static entry has zero to do with anything.



  • Setup: Cable Modem -> SG-1100 -> Laptop

    Right now we have removed the SG-1100 and replaced it with a custom build PFsense with the same configuration and it is working fine.

    My apologies, you can disregard my comment about the switching to DHCP as that is not working, I'm not sure why I said that. Also, we're having a difficult time troubleshooting remotely since the unit takes a long time when navigating the menu options.

    So when you put in the sg1100 vs the other one - you actually rebooted the cable modem.. When you change devices connected to a cable modem you almost always have to power cycle them.
