Extended Lan With multiple lans on the same network 10.25.6.0/24



  • Hi Guys i hope someone can help me.  Been trying to setup the below for a while and can never get this working correctly here is what i have is four location all with static address at different locations around the island  with static addresses from the internet service provider. What i want is to keep all of them on the same network in the event that we have a problem at one location i can easily move the domain controller  or the pbx ect…. and still keep the locations functional until a problem is resolved but when i had this setup with the tunnel everyone can talk to the server and the server can talk to every one but they could not talk to each other. i based it under this setup at this link  https://forum.pfsense.org/index.php?topic=48667.0  the only difference between mine and that one was that my ip address are all within 10.25.6.0/24 network, even the remote locations.  Can someone please help me with this? Thank you in advance

    THIS IS WHAT I HAVE RIGHT NOW

    Lets call the business name the THE COMPANY:

    THE COMPANY has four locations:  Call them Location a, location b, location c, location d, All have static address

    LOCATION A IS THE MAIN LOCATION (SERVER)

    RESERVED IP: 10.25.6.1 -  10.25.6.54 which the pfsence domain controller and other devices are using

    LOCATION A static address a.a.a.a, PFSENSE LAN ADDRESS 10.25.6.1 WITH A DHCP RANGE OF 10.25.5.5-10.25.6.104 (50 ADDRESSES)

    LOCATION B static address b.b.b.b, PFSENSE LAN ADDRESS IS 10.25.6.2 WITH A DHHP RANGE OF 10.25.6.105-154 (50 ADDRESSES)

    LOCATION C static address c.c.c.c,  PFSENSE LAN ADDRESS IS 10.25.6.3 WITH A DHCP RANGE OF 10.25.6.155.204 (50 ADDRESSES)

    LOCATION D static address d,d,d,d, PFSENSE LAN ADDRESS IS 10.25.6.4 WITH A DHCP RANGE OF 10.25.6.205.254 (50 ADDRESSES)

    You have a single DC for no less than 4 locations? You might want to read this: How Active Directory Replication Topology Works,  as well as other MS docs, and start to design something sane instead.

    P.S. If by "could not talk to each other" you mean that NetBIOS shit, then indeed that does not normally work across tunnels. Other than that, site-to-site tunnels talk to each other just perfectly fine.

    Read this: https://forum.pfsense.org/index.php?topic=36388.msg187571#msg187571 and put all those on a separate subnet, otherwise you'll produce just one giant kaboom. (If you insist, split the /24 into /22s or whatever - IMHO it just makes things much more error prone and harder to understand, but whatever you do, you need a different subnet for each of the sites.)

  • Tell me guys is this can work

    here is what we have currently:

    A= Server for B, C D    by default everyone can talk to A and A can talk to everyone

    B can talk to server A but can talk C or D so we make B a server to C and D so now we have
    B=Server  for  client C and D.  Now b can talk to every one and everyone can talk to B

    C can talk to server A  and Server B  but  cant talk to D so we make C a server to D

    C=Server for D    now C can talk to everyone and every one can talk to C

    D can talk to server A and Server B and Server C by default and everyone can talk to D

    now everyone talks to every one

    simple layout here

    Server A= Client B, Client C, Client D:
    Server B= Client C, Client D
    Server C =Client D
    Client D by default has all the others as a server and will have no clients

    I already linked what you nee to do above so that everyone can talk to everyone.
