I don't want to downplay any incompatibility issues with the Netgear
routers as I'm sure they are very real. However, I suspect these are
related to changes in the Netgear firmware IKE support ( which I know is
based on racoon ). I say this because I have a NetGear FVS338 in my lab
running v3.0.4-19 and use it to do regular testing. The howto on our
support site which utilizes Xauth + Modecfg was built using the FVS338
device, which I assure you, works fine with the Shrew Soft VPN client.
When I have time, I will try to upgrade my FVS338 to a more recent
firmware version and see if I can reproduce the modecfg problem. Until
then, I would recommend using firmware v3.0.4-19 if its still available
for download.
Hope this helps,
-Matthew
