Everything works fine for the clients but not for the pfsense by it self



  • Hi,

    I am running the pfsense actually wonderful. I have load balancing over 2 DSL lines (works)
    have a captive portal (works)
    DHCP is correctly passed to the clients
    DNS for the clients to pfsense goes well.

    Out of the view from client everything is wonderful, just the pfsense itself not resolve names, so they can not check for updates and NTP does not work.

    "Diagnostics: Ping" works only on IP addresses not names, and only when I select WAN1 or WAN2 in "Source Address" in "Default" it will not work.

    Has anyone an idea why this might be?

    Regards
    Flico

    "Has anyone an idea why this might be?"

    Where are you pointing pfsense for dns?  Which connection are you using?

    What are you using for dns?  If you for example you ask dns from connection 1 over connection 2, it most likely will not work.  Most isp's do not allow connections from outside their networks to use their dns.  What if you set pfsense to use something like opendns or googledns or 4.2.2.2 (level 3) etc..

    Can we see your routing table and what your using for dns for pfsense?



  • Here is the routing table:

    What?

    LAN    192.168.1.250 IPv4 Upstream Gateway "none"
    WAN1 192.168.1.222 IPv4 Upstream Gateway "WAN1GW 192.168.1.220"
    WAN2 192.168.1.223 IPv4 Upstream Gateway "WAN2GW 192.168.1.221"

    You have 3 interfaces all in the same network?  How is anything working??



  • That I can write in this forum, shows that it works. Im sitting here connected with this constellation.

    So what should I do?



  • I agree w/johnpoz, your LAN subnet overlaps BOTH your WAN1 & WAN2 subnets - not a good plan :o

    I would suggest as step 1 to simply change your LAN subnet to something completely different, such as 192.168.17.0/24.
    You'll have to update the LAN's DHCP server as well.
    You may have to update your firewall rules but that shouldn't be a huge issue.

    At minimum this will give a better indication of what's configured properly and what isn't.

    Try it and let us know what happens or changes.
