    I want to set up my new bought MRT54GL as a Wireless Ethertnet Bridge. Hyperwrt 2.1b1 + Thibor15c is already installed.

    Here is a schema of my network

    Computer 1 \
    - (LAN) - WRT54G - (WLAN) - Access Point at university - Host
    Computer 2 /

    A connection to the host over VPN on only one computer works fine, if the WRT54G is in Client Mode. But two VPN connections at the same time doesn't work in Client Mode. So I changed the Wireless Mode to WET, but then I can't connect to the host from any computer. A Ping to the host gets a timeout.

    * Is it possible to configure the WRT54GL that it passes through two vpn connections at the same time?
    * Has the Subnetmask on the LAN ( - WRT54G) to be the same as the SN ( of the network of the host?

    This is most likely a problem with your VPN and not with your wireless bridge. Is it an IPSec-based VPN? If so, be certain to enable UDP or TCP encapsulation, this will allow you to have two VPN connected clients behind your WRT. Also be certain to enable IPSec Passthrough.

    Thank you for your quick answer. You are right I'm using an IPSec-based VPN.

    Where can I enable the encapsulation? I din't find a possibilty to do this in my VPN client and at the router.

    You enable encapsulation in your VPN client, for example Cisco's VPN client its in the profile modification on the transport tab.

    Thank you! I found the checkbox but the transparent tunelling (IPSec over UDP, NAT/PAT) has already been enabled. Where else could be the error?
