My trusty BEFSR41 failed after many years of service (it was unable to
get IP address lease from the cable modem).  I purchased a WRT300N,
figuring that I might use the Wifi feature in the future, even though I
don't have any wireless devices right now.

So, I install the new router, change my password, disable the Wireless
features, verify that the VPN passthrough are enabled.  My 2 PC's
(running XP Pro) in the LAN can access the internet just fine .. until I
initiate VPN (Cisco client) on the PC I use for work.  As soon as that
VPN is established, I lose all connectivity on that PC.  I cannot ping
any devices at work or on the internet.  I even disabled the firewall
features on the router, but to no avail.  All functionality was restored
when I disconnected from the VPN.

I returned that router and installed a WRT54GS.  Everything, including
VPN worked right off the bat (I changed the password and disabled
wireless on this as well.).  Again, VPN passthrough (all 3 protocols)
was enabled (by default) in both routers.

I can only conclude that there is some bug in the WRT300N firmware.

The hardware and firmware versions of my devices were:

WRT300N: ver 1.1 Firmware 1.51.2 dated 6/4/07
WRT54GS: ver 7.0 Firmware 7.50.0 dated 3/20/07

Any ideas, comments?
