Hi,

  • on Computer A I have last version comodo and IIS with running web site
  • on Computer A I can go to my web site (localhost)
  • on Computer B I cannnot open my web site from Computer B
  • but when I turn off comodo firewall, it’s ok
  • I have tried add rule to global rule (allow tcp, udp and both, from any ip to any ip or Computer B’s ip, from any port to 80 port) and to applications rule, but it doesn’t work

What can I do more?

(Computer A → win 8.1, Computer B → win 7)

Thanks a lot for your help
