Rules for multi lans with different subnets[SOLVED]



  • trying to set a 5 nic setup
    have
    wan, static ip from isp
    lan static ip 192.168.0.4
    opt1(subnet172) static ip 172.16.0.1
    opt2 (kidssubnet) static ip 192.168.5.1
    opt3 (wifi) access point ip 192.168.0.55 dhcp enabled
    rules
    lan
    default anti lock out and allow lan to any

    • LAN net * WIFI net * * none  
      ICMP   * * LAN net * * none

    wifi opt3
    ICMP   * * WIFI net * * none   allow ping firewall pfsense_AP

    • WIFI net *      * * * none   allow clients on AP to access clietns on lan and wan
    • WIFI net * LAN net * * none

    opt2 kidssubnet

    • KIDSSUBNET net * * * * none   allow to all other interfaces  
      opt1 subnet 172
    • SUBNET172 net * WAN address * * none   allow 172 to www

    so what is happening is through pfsense i can ping opt2,3 from lan and back
    but when the wifi gives a ip out i cant ping the pfsense box or see the internet
    from the lan cant see the internet
    what i want is the lan to see the internet and opt2,3 see lan and internet
    and opt 1 to see the internet but not the lan,opt2,3



  • sorry hit enter and post before finished any help or rules to create this would be great thanks



  • What is your subnet masks with lan and opt3? did you try to bridge those?



  • @Metu69salemi:

    What is your subnet masks with lan and opt3? did you try to bridge those?

    subnet /24 yes tried to bridge and works. would like to keep the wireless separate from (lan if i can)
    once this all works want to filter each interface using squid and squidgaurd or dansgardian 
    so i can can control where kids go



  • Can you change subnet for wireless then if you want to separate it from lan.
    Based on rules there should not be any problems. Can you try with subnet change and inform if this problem still exists



  • will change subnet on wifi and see what happens



  • changed subnet on wifi to 192.168.6.1 amd set dhcp 192.168.6.50 - 75
    net book connects and get ip can't ping any other interface and can't get web
    can ping interface ip of 192.168.6.1 but thats it. so dchp is working but nothing else
    same rules apply

    wifi

    • WIFI net * * * * none   allow clients on AP to access clietns on lan and wan 
      ICMP * * WIFI net * * none   allow ping firewall pfsense_AP


  • ok lan to the wan is working can get internet services going to reconfigure mail server to use pfsense
    but still can't get wifi to get out to internet
    going to set the other interfaces up and see
    thanks for the help seem to be going in the right direction



  • Can you do tracert from wifi clients to see where it's halting?

    One place worth to look at is Firewall:NAT and edit there manual outbound nat in use. You should see there automatic rule for lan net, you can add all others there too.



  • ok found the problem had the gateway for the wifi set wrong fixed and working
    got 4 interfaces working out of 5 got some quirks to iron out but i think i got this figured out (as usual making it more complicated than needed)
    got another problem trying to get my other opt(subnet172) to go to wan and not any other interface
    rule for subnet172

    • SUBNET172 net * WAN address * * none   allow 172 to www

    should i change wan address wan subnet or?
    trying to prevent subnet172 access to other interfaces except wan
    once again thanks getting closer to my goal  ;D ;D



  • Easier way: create alias localnets. add every single localnet on that

    then create two rules:

    1. block any wifi localnets
    2. pass any wifi *

    that should do it

    i have 5 interfaces
    wan
    lan
    opt1subnet172
    opt2kidsSubnet
    opt3wifi

    dont understand what you mean
    i want to block another opt(subnet172) not wifi to all interfaces but wan
    so if i read what you are showing create a alias and add all subnets include subnet172 and change wifi to subnet172 and this should work



  • think i got this do i put the rules under opt(subnet172) or under wan
    i think this should go under subnet172
    just making sure thanks!!!



  • Yes but it only to that interface subnet172

    In pfsense rules are working on ingress. That means, if you add rule to LAN, it doesn't affect to subnet172



  • everything seems to work just got some fine tuning
    and setting some filtering for parent control
    thanks for the help!!!!



  • no problems
