Hi,
I have VPN tunnel established between 2 ubuntu 16.04 PC, which has 8 connections b/w them.
Even if i dont sent any traffic via tunnel, i see 86KB of data per minute, i am not sure whether these are keep-alive messages or sync messages.
i see both TCP and UDP traffic transferred continuously, can you please help in suppressing these traffic.
Thanks,
Venkatesan.

Re: softether vpn tunnel keepalive message suppression
Could you show more detail about configuration and network environment?

Re: softether vpn tunnel keepalive message suppression
Sorry for the delay,
declare GlobalParams
{
uint FIFO_BUDGET 10240000
uint HUB_ARP_SEND_INTERVAL 5000 <==================>
uint IP_TABLE_EXPIRE_TIME 60000
uint IP_TABLE_EXPIRE_TIME_DHCP 300000
uint MAC_TABLE_EXPIRE_TIME 600000
uint MAX_BUFFERING_PACKET_SIZE 2560000
uint MAX_HUB_LINKS 1024
uint MAX_IP_TABLES 65536
uint MAX_MAC_TABLES 65536
uint MAX_SEND_SOCKET_QUEUE_NUM 128
uint MAX_SEND_SOCKET_QUEUE_SIZE 2560000
uint MAX_STORED_QUEUE_NUM 1024
uint MEM_FIFO_REALLOC_MEM_SIZE 655360
uint MIN_SEND_SOCKET_QUEUE_SIZE 320000
uint QUEUE_BUDGET 2048
uint SELECT_TIME 256
uint SELECT_TIME_FOR_NAT 30
uint STORM_CHECK_SPAN 500
uint STORM_DISCARD_VALUE_END 1024
uint STORM_DISCARD_VALUE_START 3
}
Is there a way to change the above config "HUB_ARP_SEND_INTERVAL" after i establish the tunnel.
My requirement is to change the tunnel setting dynamically without tearing down the connection.
Thanks,
Venkatesan.

Re: softether vpn tunnel keepalive message suppression
Is the traffic which you said ARP?

Re: softether vpn tunnel keepalive message suppression
Looks like yes, because when i set it to "60000", my idle tunnel traffic becomes very less.

Re: softether vpn tunnel keepalive message suppression
Could you try ' NoArpPolling' option?
