Sounds like the firmware in the router can't handle VPN over the radio.

Is this an older model router (a year+) ? Perhaps there is a firmware upgrade
for it. Linksys and D-link routers all had this problem when they first got
in to these home units and firmware upgrades fixed everything fine.

Well I got it to work after messing around with the VPN client. In the
tunnel properties you can either specify which card to use and it was
defaulted to "Any Interface". Even though it should have worked for
either wired or wireless (same machine, not both connected at same time
except when I had to use wired), I had to specify the wireless card as
the card to use. Strange that "Any Interface" doesn't really mean any
interface apparently.

My wireless card is an internal Dell TrueMobile. As long as the
wireless works, I'll just use that all the time to connect now. Thanks
for taking the time to respond.

I have used Linksys and Dlink wireless routers with out-of-the box firmware
for quite some time to connect via SonicWall, Nortel, Checkpoint, and
Microsoft VPN clients.

Some other possible thoughts are that the wired IP address is set up in the
DMZ on the router, or that the timing is just a little slow from wireless,
and the VPN server has timing parameters set too tightly. That would have
to be adjusted at the VPN server side.

Are you trying to connect both wireless and wired at the same time? Some
routers only allow one VPN tunnel, although I haven't seen that problem.

Your NAT router is going to present all of the addresses on your private
network as a single IP address to the internet, and do some port management
to keep them differentiated internally. The Nortel server that I connect
to makes note of "IPSec NAT Transversal: Active on port 10000" for the
first connection. The VPN server might also be seeing a second attempt
from the same IP address, and only allow one. Mine allows only two.
Sometimes if I am having connection troubles (like a marginal wireless
connection), I can get blocked from reconnecting for a little while because
my reconnect is seen as a violation of the "only two" rule.

Is the wired connection that works the same machine? If not, can you
rearrange connections and IP addresses to try the lowest IP address as
wireless?

I would certainly update the firmware to the latest rev.

After installing the wireless card, removing and reinstalling the VPN
client package might allow it to recognize all of the interfaces.
Adding a card to an existing VPN system doesn't seem to work as reliably,
even though it is set for "Any Interface".

From Belkin's product literature, available at
<http://www.belkin.com/support/download/download.asp?cat...
ode=>, it looks like the 7230 is the first of their wireless boxes to
advertise VPN pass-through. You'll probably need to replace the 6230
with something newer.
