    First time poster so please be kind .... about 4 months ago my router died and I decided to buy a WRT54GS everything worked fine got rock solid wireless connectivity in the house can even use my laptop in the yard !! Only problem I have is with wife's laptop, she works for financial institution and they use VPN to connect to their network resources and Email. My problem is the laptop gets on the internet just fine but never finishes to log on to the VPN..... When she contacted the VPN support line they told her they don't support routers so they wouldn't even talk to her... so I thought this was the end of the story then a coworker of hers told her that she has a Netgear router and with no tweaking she can connect either wired or wireless !! Sorry for this long message but my question is what can I do to get this freaking VPN client to get authenticated? If I connect directly to the cable modem I have no problem...
    Thank you all
    P.S. I did upgrade to the latest BIOS a few days ago but no change

    I do not have an answer but can confirm that my 54GS is connecting fine to my VPN. It is a Cisco VPN3000 client.

    I do know that some people have to enable ports in the router, but I did not have to. Anyway, the Linksys is just fine here.

    Make sure that "VPN Passthrough" is turned on for IPSec. If it is not, the Linksys will not allow the IPSec packets (these carry the data) to traverse the firewall.

    I'm not using the standard firmware on my WRT54GS, but if I recall correctly it is somewhere under the Setup/Security tab on your Linksys.

    Re: tried it already

    Not much more to do then...at least on your router. If you are using the Cisco VPN client, it will (if you leave the default settings) automatically negotiate NAT-T (NAT traversal) with the VPN server, *if* that VPN server has been set to allow for "IPSec over UDP". While your wife's IT department might not support routers (silly comment on their part), if they are halfway competent, and if this is a Cisco solution, they should be able to set this up no problem. Of course that's two "ifs" in a row but you know.....

    I've done this another time and in fact am now doing it to my PIX firewall at home while sitting in my hotel room. I have found that this way I can traverse any kind of PAT'ng devices without having to worry about VPN passthrough.

    Gets more interesting

    I just borrowed from a friend a Netgear WGR614 Wireless router and out of the box with no tweaking the laptop connects to the VPN both wired and wirelessly.... weird, so it's nothing on their end I would have assumed that since CISCO owns Linksys somenthing like this shouldn't have happened, I would like to make this work but not sure what else I can try !!!
