Routing Between Subnets - Just Doesnt work :(



  • Hello All,

    I have just installed pfsense (pretty amazing product by the way :) ) but I haven't managed to get it doing what I hoped. Here is my setup:

    Internet Access: 192.168.1.254 (Sky Router)

    The above sits on 192.168.1.0/24.

    I have Hyper-V on a machine running Server 2008 R2. This has two Virtual Networks. One is internal the other is External and mapped to the network card on the 192.168.1.0/24 network. PF Sense is installed in the External Network and has a second network card that sits in the internal. The network configuration is as follows:

    WAN: 192.168.1.202
    LAN: 192.168.50.1

    So here is the troubleshooting information:

    From 192.168.50.0/24 I can ping all local devices and both IP addresses that are assigned to PFsense.
    From 192.168.1.0/24 I can ping the PFSense device.

    From PFsense I can ping and access google and all devices in 192.168.1.0/24 and .50.0/24.

    However I am unable to ping or access anything in 192.168.1.0/24 from the 192.168.50.0/24 network.

    I have created a firewall rule on the LAN interface that allows all traffic from .5.0/24 to all destinations to no avail.

    Any ideas?

    Cheers

    Paul



  • Did you disable the blocking of private networks on the WAN interface?



  • Hi Podilarius,

    I have yes. Still no luck :(

    Cheers



  • Are you firewalling or just doing simple routing? You might have a split route if the server in 192.168.1/24 is not using 192.168.1.202 as a gatway to access 192.168.50/24. You will probably need either a local route or a route setup in 192.168.1.254 to point 192.168.50/24 back to 192.168.1.202.



  • Thanks Podilarius, that is probably the issue. When I tracert, I get a reponse from 50.1 but nothing after that. Checking the firewall logs, the data is passed through.

    The only issue is, I cant add routes to the sky router :'(



  • You can add a route to the server to test.
