SoftEther VPN sends broadcasts to all client because SoftEther VPN is L2 VPN.

SoftEther has data compression function. ... on_Setting

Hello, ... ompression

Using Data Compression

SoftEther VPN protocol can compress sent and received all Ethernet frames internally and transmit them. The deflate algorithm developed by Jean-loup Gailly and Mark Adler is used as the data compression algorithm. The compression parameter is set so processing is executed at the fastest speed.

By using data compression for VPN communications, a maximum of 80% of communications volume can be reduced (depends on protocol used). If compression is conducted, CPU load of both client and server becomes higher, and depending on the performance of the various types of hardware, if the line speed exceeds about 10 Mbps, in many cases not compressing data improves communication speed.

How can i make compression 80% i only have 12%

My network scenario like this:

Location-1 Server side :
"assigned to this NIC all subnet"


Location-2 Bridge:
Lan :
Bridge network : using both subnet ,

what is required to decrease broadcasting in this network and make location-2 using for some PCs IPs from location-1 WAN subnet

If you can specify the profile of the unnecessary broadcast, the VPN server can drop these by "Access Lists".
