    Hi victor.

    I'm so sorry about writing like this the problem is that, to see  the server I have to travel around 50Kms... an I only can go in the weekends. (so remote server)

    Ok the PPTP server is working so good and in the default ports. I can connect to the server with the last comand that you gave me.

    But When I try to make ping or reach the server in http://myserver/server-manager

    The screen of the server shows me this:

    vrmr: DROP in policy IN=eht0 OUT= MAC=ff:ff:ff:ff:00:02:a5:9c:97:11:XX:XX
    SRC: 192.168.181.243 DST=192.168.181.255 LEN=79 TOS=0x00 PREC=0x00 TTL=120 ID 141
    66 PROTO=UDP SPT=137 DPT=137 LEN=50

    Have any idea?

    Thanks.

      This appears to be smb browsing. This needs to be able to talk to the broadcast address, as you can see here: 192.168.181.255. Support for broadcasts is a bit hackish in Vuurmuur (I plan to replace this). What you need is a rule like this:

      accept service samba from local.lan to firewall
      (where local.lan is the network 192.168.181.x)

      This will make sure the broadcast address is also allowed because in the samba service the 'broadcast' flag is enabled.

      As for the ping, that must have a different reason, so please paste a log of that as well.

      Cheers,
      Victor

      This is a part of the log I try to change certain IPs.

        I'm not sure what you expect from me here. I see a number of dropped connection attempts to TCP port 1999, 2000, 2001 and 55776. What are these connections? Did you try adding services for them?

        Cheers,
        Victor

      At the end I make it work, the problem is to understand the SNAT rules for the new interface.

      Now I have a sistem to make probe, so I'll try to make an rpm to the SME, I hope that the SME-server developers will like it.

      Thanks a lot for Your time, such a great tool.
