Firewall's blocking a homepage.



  • Hello, first of all i want to apologies for my more then crappy English :)

    The problem i have is that PFsens's blocking a regulare homepage "whitout any aperent reason" and just to clarify this is a corporate homage whit out any suspicious stuff.
    I try to get anything out of the logs but there's nothing there abute the destination but when i ping the site i get this result.

    PING server1.xxxx.se (81.201.219.xxx) from 81.170.214.xxx: 56 data bytes
    36 bytes from h-214-226.A163.corp.xxx.se (81.170.214.xxx): Communication prohibited by filter
    Vr HL TOS  Len  ID Flg  off TTL Pro  cks      Src      Dst
    4  5  00 5400 ab4d  0 0000  3f  01 7b03 81.170.214.xxx  81.201.219.xx

    But that's not giving me any good information abute what's going on and why it's blocked.



  • Have you created any rules on the LAN or WAN blocking traffic?

    Isnt the bold part a response from the router blocking your ping?
    Seems to me like your ISP is blocking it.

    No blocking rules at all

    I just tested whit the other router/fw whit the same ips and that worked just fine.
