[SOLVED] Strange Route issue (No network from LAN, while working from WAN)

  • Hi, guys!
    I have the following situation:
    ADSL modem is providing my pfsense box with Internet, there IS ping from WAN to any Internet site, but no such ping from LAN-side of the network. The strange (some would say funny) thing is that I am outside of the country, and I can access the router via the WAN interface and manage it, but none from LAN could do anything in Internet. More technical details:

    ADSL modem: internal IP , DNS is automatically assigned to its internal network interface

    pfsense WAN (rl0): set in Interfaces -> WAN  type: DHCP, DHCP client configuration - set the name of the router itself, and both ticks on "Block private networks" and "Block bogon networks" are checked on (marked)

    pfsense LAN (rl1) : set in Interfaces -> LAN type: static, address: ; Gateway:

    $ netstat -rn

    One side detail is, like I said, that I am 1400 km away from this machine, and have no physical access to machine, which made ~67 days uptime, before rebooting for unknown reason. I know this may seem unrelated to the problem, but I am trying to clarify all the details that one wants to be provided with. Let me know what do you need as another info, I will supply it.
    Probably the trouble is obvious and very easy to be solved by somebody skillful, but I can not see the reason for failure to connect LAN to WAN - somehow something went wrong… Please note, that I haven't made any changes regarding routing in recent 3 months.
    So in conclusion - I would like to ask for an advice how to fix this issue remotely. Thank you very much in advance!

    Found some old config file - couple of days old, restored from it and after some time, so far the system is working, and connected from LAN to Internet. So I am sorry for making a lot of noise for no-thing. Anyways, thank you very much indeed for attention, and keep smiling, guys and girls! :)
