Hi,

Both server and client get same message,

After connected, the server show the following log:

Problem Now: PFSense box connected but the client machine LAN A to LAN B are not connected.. It is i less some step??

Client Site: -
Share Key Config

yce_kelvin

This is the server share key conf

Note: 192.168.10.0/24 is server site
192.168.1.0/24 is client site
192.168.100.0/24 is vpn tunnel subnet ….

Follow-up-note:
We where able to solve the problem per MSN.
yce_kelvin forgot to mention that the server had more than one WAN.

http://forum.pfsense.org/index.php/topic,7001.0.html

The rule on the LAN had as gateway a loadbalancing-pool.
The problem was solved through adding another rule with as destination 192.168.1.0/24 (subnet on the client side) and gateway * above the rule with as gateway Loadbalancer. (see screenshot posted by yce_kelvin below)

Site to site connection with share key is okay but cannot bridging.
Try to do another site-to-site bridging. If some one have experience before kindly share ur exp here. Anyone success before?

Anyone success with openvpn tunnel and lan game within 2 lan's client pc?

GruensFroeschli

Nobody will ever be able to use UDP broadcast based LAN games in a routed scenario.

You NEED a bridge, or else a UDP proxy like this one: http://www.vttoth.com/tunnel.htm

In about 3 weeks or so i will have a bit more time. If i'm not too busy with other projects i think i'll try to get this running since i'm interrested in this too.

Bridge mode can successful for 2 LAN sites in a "normal" condition. "Normal" mean a normal office or group network. If those client is "cloned" then will meet the problem with MAC address issue. This is because if the PCs are cloned, that mean the MAC address also will duplicated.

Bridge mode i use is form a pfsense as openvpn server and other client pc install openvpn with tap-adaptor. Client can be successful connected but need a different MAC address of TAP-adaptor. I m try to come out a script that can make the TAP-adaptor MAC address can change according to IP address.

But, what i hope that is 2 site PF sense can form bridge mode and no need to do any setting or installation to the client PC.. It is possible.

I know that PFsense routed VPN is not work with what i want.. Anyway i hope that i can make a successful case under GruensFroeschli help :)

or someone interest on it can study together. My network knowledge is level 1 only ^^
