softether vpn tunnel keepalive message suppression

Post by venkat.siva » Tue Jan 16, 2018 5:08 pm

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.

Could you show more detail about configuration and network environment?

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.

Is the traffic which you said ARP?

Looks like yes, because when i set it to "60000", my idle tunnel traffic becomes very less.

Could you try ' NoArpPolling' option?
