Internet help please and thank you



  • I have pfsense installed on a old amd sensations system with a usus mobo, 1GB ram, 40GB IDE HD, amd 1009mhz cpu x86, 2x realtek RTL8160SB N.I.C's. My network schematic looks like this.

    ISP>modem>WLAN>LAN>HUB(switch)>PC  My isp is static
    Ihave set the nic's in setup as re0 Wlan & re1 for LAN

    my ip's are WLAN
    192.168.1.2
    255.255.255.0

    LAN 192.168.1.1
    255.255.255.0

    PC
    192.168.1.3
    255.255.255.0
    192.168.1.1

    63.2XX.2XX.2XX(isp)prefered dns
    63.2XX.2XX.2XX(isp)alternate dns

    Ok, i can access the G.U.I, But wont load web pages, i can ping my pc from pfsense,but cannot ping pfsense from pc??
    i have enabled net bios over tcp on my pc, Also my Wan led light blinks sometimes but Lan never does, tried fifferent nic's, re-installed pfsense, scoured support pages and googled for hours, So sory if this is a recurring post but i am at loss here. i am not networking or Linux expereinced although i do know a little to get around or understand some things.

    Thank you for your time, experience and patience  i appreciate it ALOT.



  • Sorry BSD Guys i meant UNIX



  • Update i re-installed and auto configured my nic's , and switched my ip's around and now i can ping wan,lan and pc but still no internet ??? i messed around with the firewall settings no web. i checked the status of my connection and i am recieving and sending around 400,000?? What gives?



  • I'm going to assume you mean WAN by WLAN.
    I'm going to take another guess that your Modem is running nat. The first thing you need to do is use a different network for the LAN. If you WAN is on 192.168.1.x, then use 192.168.100.x or something- just don't use the same as the WAN.
    /* begin IP 101 digression
    The devices that are directly reachable from an interface are determined by the IP address and the subnet mask.
    If an interface is set to 192.168.1.1/24 it means that 192.168.1.1-192.168.1.254 are reachable from that interface. If the other interface is set to 192.168.1.2/24, then it will try to send traffic for 192.168.1.1-192.168.1.254 out THAT interface. Both interfaces think the same machines are connected to them- this makes the firewall insane and useless.
    end IP 101 digression*/
    If you can get past this point, you might want to do a little more reading to see if you can turn off nat on the modem and get rid of the double-nat.
