SecureNAT vs ISP MAC control

Post by AntonK » Fri Jun 26, 2015 3:50 pm

Hi. I have SecureNAT enabled to use Softether for internet access through VPN. ISP which server uses controls MAC adress, server itself connects to internet just fine but any VPN client gets redirected by ISP as device with unknown MAC and does not gives access to internet.
Can`t figure out where is the problem,

I don't think it is anything about MAC control because routers replace the MAC address with their own when doing routing.

Please disable Kernel-mode SecureNAT.

Thanks, not it works, sort of...

Both links are 100mbs but speed drops to 0,5mbs and latencies are cosmic. It becomes unusable.

Have any directions?

Try to add a tap device and do nat with linux routing and iptables instead of SecureNAT.

Disable SecureNAT. Install Softether VPN Client. Add a virtual adapter. Connect to itself with no adjustment of routing tables in the advanced settings on system startup and configure internet sharing in your WAN adapter and select the virtual adapter as the adapter for LAN.

This sounds like clutches. Neither of my clients will be windows machine. Just tested it on ipfire routed and with lg d802. Same result painfuly slow unusable internet access.
