    Hi,
    a new package is available as New Feature for Zeroshell 3.0.0.

    This package includes special tunings for Connection Tracking module that allow Zeroshell to perform better processes such as:

    – Stateful Firewalling
    – Traffic Shaping
    – Routing with NAT enabled

    You should install this package in any case, but especially if:

    – You want to take advantage of the installed RAM to speed up the connection tracking.
    – On the LAN there are VoIP applications that use SIP or H323 protocols. In fact, these protocols require to be tracked to be correctly forwarded in the case the NAT is active.
    – You notice a high load average of the system when the Firewall is processing a large number of TCP/UDP connections. This could be due to DDoS attacks or the presence of P2P traffic.

    Regards
    Fulvio

    I am using ZS since 1b14 with Linksys PAP2T ATA (SIP adapter) and in all these years I never needed to set up NAT for the ATA. It simply works fine without any settings on ZS side, don’t know why.

    Also, there is a lot of P2P traffic on the net and the machine ZS runs on is very low on CPU utilization (it’s P4 2.2 GHz with 512 MB RAM).

    The connection tracking for VoIP connections is automatically performed so you do not have to take any action.
