Replace HUBs by SWITCHes (Feature request)
Posted: Fri Mar 28, 2014 4:29 am
Hello,
I am using SoftEther Client Version 4.04 on Ubuntu 10.04.4 LTS (x86/32 Bit). It works fine. Thank you, dnobori, for this great software!
After connecting to vg1868122484.opengw.net via SSL-VPN and starting tcpdump on my virtual interface I see a lot of traffic not related to my computer, but to approx. 100 foreign stations. In a quick look I identified:
- ARP requests and answers
- DHCP request and leases
- TCP/IP packets TO stations on the HUB
- and more (but no TCP/IP FROM stations on the HUB)
This traffic is useless. It is wasting bandwidth and violates privacy. May be it is a security risk.
To improve your software I suggest: Replace the soft HUBs in your server by soft SWITCHes.
