VPN with local bridge

Post by votes » Tue Apr 30, 2013 9:01 am

Hi.

I have problem to run VPN with local bridge.

If I use Secure NAT with dhcp all works fine, but I get private address for client and when I connect to internet all clients have this same public IP address (server public IP). I have many public IP and I need use them - one per VPN client.

So I try use VPN Server with local bridge and own DHCP server on LAN

I instal vpn server, configure local bridge with free ethernet intrface.
(I see MAC from LAN in manage sessions - i think this step is fine)
I use default settings - secure nat off dhcp off (use dhcp on LAN)

Client get IP address from bridged LAN dhcp server (still OK) but I can't ping and connect to any other LAN computer or use local LAN gateway to go to internet.

I reeded documentation few time but I still can't do this
I need help :)

Local-bridge have some limitations.

1. Most of Wifi adapters don't enter promiscuous mode.
2. In virtual machine, you need some configuration to use promiscuous mode.
3. In UNIX OSs, local-bridge can't transfer packet from virtual hub to the host itself.

If above cases don't match, please check packet log to determine where the ping packet losses.
