    We are currently support first biggest Games Center in Vietnam with 220 PC Games.

    We deploy with RV-016 to loadbalancing 07 ADSL lines from 02 Service providers with Center Management Switch SRW224G4

    Other 12 SOHO 24 Port Switch 10/100 are connect to SRW224G and to PC Games.

    The network is netmask,
    IP of RV-016 ->

    Currently we have problem that some time, very frequently the PC Games were unable to connect to RV-016, and Internet Access was lost for all network

    And this time ping to RV-016 was timeout fro 1,2 minutes, then connect again

    I wonder that, there could be that RV-016 maybe out of memory for concurrent session.

    There reason would be the default session timeout in RV-16 were setting too high

    We see the similar problem with WRT54G, WRT54GS before with original LINKSYS firmware, with default setting

    echo "600 1800 120 60 120 120 10 60 30 120" > /proc/sys/net/ipv4/ip_conntrack_tcp_timeouts

    Table 4-2. Internal states

    State : Timeout value
    NONE 30 minutes
    ESTABLISHED 5 days
    SYN_SENT 2 minutes
    SYN_RECV 60 seconds
    FIN_WAIT 2 minutes
    TIME_WAIT 2 minutes
    CLOSE 10 seconds
    CLOSE_WAIT 12 hours
    LAST_ACK 30 seconds
    LISTEN> 2 minutes

    the established timeout was 5 days

    and then with third-party firmware, we able to set the established timeout of TCP connection to low time such 180 or 600 second , and increase the max-concurrent session upto 2048 or 4096 ...-> then WRT54G/GS disconnect problem were solved

    but with RV-016 we do still do not know about max-concurrent session and established timenout
    Please advice about those parameters of RV-016, and help me to any solution to troubleshoot our problem with this kind of very big Game Center
